Geeksphone to start selling Firefox OS Developer Preview phones on April 23

Mozilla, Geeksphone and Telefonica have been working together to create a Firefox OS developer preview phone, and we’re excited to say they will go on sale April 23rd. With early access to hardware, developers can test the capabilities of Firefox OS in a real environment with a mobile network and true hardware characteristics like the accelerometer and camera that are not easily tested on the Firefox OS Simulator. Plus, new hardware is fun to play with!

The Firefox OS Developer Preview Geeksphone devices have development versions of Firefox OS and are are unlocked so that developers can use them wherever they are in the world and they are updated regularly with the latest Firefox OS build. This will enable developers to explore the potential of the open Web and to bring the power of the Web to mobile for billions of users worldwide.

Two developer devices

Geeksphone has two Firefox OS developer devices for sale, the Keon and the Peak. Both phones can be bought online and shipped to just about anywhere in the world. The Keon has similar specifications as the actual target hardware that operators will ship in the phones they roll out to consumers later this year. The Peak offers a slightly more high-end device for developers wanting to experiment with apps for devices that might be commercially available in the future.

The Keon is an orange (like Firefox!) phone with a 3.5″ screen Qualcomm 1Ghz processor and 512 MB of RAM. It’s available for €91 plus taxes, shipping and handling.

The Peak has a slightly larger screen (4.3″) and a Qualcomm DualCore 1.2Ghz processor. It costs €149 plus taxes, shipping and handling.

Both phones can be purchased directly from Geeksphone. Support and updates will also be provided directly by Geeksphone. Of course you can visit the Mozilla Developer Network for more information about Firefox OS and the Firefox Marketplace Developer Hub for information on how to build, publish and submit your open web app to Firefox Marketplace.

Existing web apps

Developers have already built and published awesome mobile web apps that you can check out today on the Developer Preview phone. We expect that these developer devices will inspire and enable even more. For some examples, you can check out the Marketplace for apps by indie developers that solve cool problems like:

Or try these indie games or challenge yourself to write your own game:

You can create an app for Firefox OS by making some small changes to your existing website. As Alexander Saladrigas said last weekend, “It was exciting to see Firefox OS in action on hardware that will be representative of the final commercial devices. I remember several devs pushing their web apps made for browsers or other platforms with the only addition of a tiny JSON manifest… and it worked flawlessly on the first try. I thought ‘Wow, that easy? Just as any web page?”

Although, it’s great to have the actual hardware to test your apps, if you’re not in a position to purchase a Geeksphone at the moment, you can still try out Firefox OS and your app in several other ways:

  • Install Marketplace for Android on your Android phone. (Your friends and family can also do this – it’s as easy as installing an app, so they can try out your app too.)
  • Use the browser-based Firefox OS Simulator to view and test your mobile app on the desktop.
  • Install Firefox OS on your own hardware.

Why develop an app for Firefox OS?

  • Keep the web open. Support the open web and help make sure the power of the web is available to everyone – even on mobile devices.
  • Simplicity. Develop on a single technology stack (HTML5/CSS/JavaScript/new WebAPIs) and deliver across the web and devices.
  • Freedom. You’re not locked in to a vendor-controlled ecosystem. You can distribute your app through the Firefox Marketplace, your own website, or any other store based on Mozilla’s open app store technology.

If you have any more questions, please read the Firefox OS Developer Preview. Below is also a helpful FAQ on Geeksphone.

We look forward to seeing what awesome apps developers make for the mobile open web. Happy hacking!

Q. Will Geeksphone ship to any country?

A. Yes.

Q. Who is Geeksphone?

A. Geeksphone is a Spanish company dedicated to designing and manufacturing latest generation smartphones. It was formed in 2009 and was the first European company to develop a smartphone featuring Android OS.

Q. What is Telefónica and Mozilla’s involvement?

A. Telefónica and Mozilla worked closely with Geeksphone to make it possible to manufacture these developer test units.

Q. Why do you need these devices?

A. Making preview developer devices available is crucial to ensure a rich ecosystem is ready when handsets launch for the mass market. The Geeksphone devices will allow developers to test the capabilities of Firefox OS in a real environment beyond the facilities provided by current emulators. It will be possible to test some characteristics like real performance and interaction with the mobile network.

Q. Are these the first ever Firefox OS devices?

A. Through the development of the project Firefox OS has been ported onto a number of different devices from different OEMs in order to test and demonstrate. This is the first time that developer handsets have been made available for developers working outside of the project to take away and test their applications. Today’s announcement does not represent a commercial launch for Firefox OS. These will take place later this year.

Q. Can consumers get the Geeksphone handsets?

    I’m presuming the price in the US will just be a direct conversion from Euro to USD excluding VAT? Also, is there any word on how much S&H will be to the US? Also, what are the accepted methods of payment at the Geeksphone store?

    April 22nd, 2013 at 23:12

    1. Robert Nyman [Editor]

      I believe the price should be a conversion, but I don’t know. With your questions, it’s best to contact Geeksphone who will be able to answer your questions.

    looks like the base model sold out super quick. I had a phone in my shopping cart but the credit card payment system kept declining my payment for some reason. Came back 30 minutes later to try it again and the base model was listed as sold out.

    Mixed feelings about that. Good to see that much interest for Mozilla. Bad to see that much interest, because I didn’t get one of the first batch of phones and I’m wicked jealous. I even went to all the trouble to get purchase authorization from my home financial officer (ie my spouse), instead of trying to hide it by laundering the cost it through my discretionary coffee budget.

    If you could do a follow up with information on when the next batch will become available that’d be great. Better yet, just let me know before anyone else so I can be sure to get one in the next batch.

      It appears they are back in-stock :D

      April 23rd, 2013 at 01:55

    2. Robert Nyman [Editor]

      Thanks for a very honest comment. If possible, and as stated by others, I believe you should try again, there should still be some left.

      April 23rd, 2013 at 05:00

      1. Robert Nyman [Editor]

        Correction: they seem to be out of stock now, sorry for that.

    Jef, take another look, the Keon is listed as in stock again.

    April 23rd, 2013 at 01:49

  4. Adam

    Just to clarify, is this a phone that you develop on, or does it just let you see what you’ve developed conveniently on a mobile platform?

    I can’t help but think what a nightmare it would be to write code for hours on a phone…

    April 23rd, 2013 at 02:13

    1. Robert Nyman [Editor]

      It is a phone on which you can test Open Web Apps that you have developed – more about that in Getting started with Open Web Apps – why and how.

      April 23rd, 2013 at 04:59

  5. Tojo Chacko

    Looks like everyone wants to get their hands on this phone :) The shopping portal says closed for maintenance. When will it come up again?

    April 23rd, 2013 at 07:21

    1. Robert Nyman [Editor]

      Soon, I believe.

      April 23rd, 2013 at 07:51

      1. Javier Agüera

        We expect to be relaunching the online shop at 3pm CEST ; we will keep you posted!

    When I Can Buy It In China Mainland??

    April 23rd, 2013 at 08:26

    1. Robert Nyman [Editor]

      If you mean buying it in stores, these phones will only be sold online.

  7. Javier A

    Dear all,
    I’m Javier Agüera, CTO of Geeksphone
    First of all, thanks for your amazing support! We were very positively surprised because of the welcoming of the devices
    There have been some issues that may have raised because of the confluence of users. We will be solving each one personally, so pelase address sat(at)geeksphone(dot)com for any issue.
    Euro/Dollar conversion shall be working, indeed it’s programmed so that there is a fixed rate and you can choose. VAT is only applied for European Union countries, for the rest of places UPS may notify and charge the relevant taxes on the reception of the devices (but in our experience only happens if purchasing in bulk).

    And good news for those of you that are eager to purchase your device but wasn’t able to do so! Store is reopening in just a few hours. We will let you know by Twitter with some time in advance!

    Best regards, and thanks once more for your understanding

    Q. Will Geeksphone ship to any country?
    A. Yes.

    I think that’s not true. They are not shipping to Pakistan. I was very disappointed by that because I was waiting for these devices for long time :(

    April 23rd, 2013 at 10:32

    1. Javier Agüera

      We do ship to Pakistan, but you need to address us directly as special shipping proceduras shall be arranged.
      Sorry for the confuson if any!

      April 23rd, 2013 at 16:22

      1. Fawad Hassan

        You mean I have to send email to because I didn’t found any option for Pakistan in the dropdown?
        Thanks :)

        April 24th, 2013 at 01:16

      2. Fawad Hassan

        Ok found it. It’s now added in the dropdown. Thank you very much!

        April 24th, 2013 at 12:20

        1. Javier Agüera

          Our pleasure :)

    Will any sim card work with the Peak model? Because in the specifications on this link its mentioned that Keon is unlocked, but nothing is specified for the Peak model.

    April 23rd, 2013 at 11:36

    1. Javier Agüera

      Both models are 100% unlocked and work with standard SIM cards

  10. wemo

    I love Firefox, but I don’t see a need for another mobile OS and ecosystem.

    April 23rd, 2013 at 12:22

  11. Mark Coggins

    Wemo, our goal is to make the web the platform for mobile as well, so we don’t see it as introducing a new ecosystem as much as moving an existing one to mobile.

    April 23rd, 2013 at 13:58

    1. Alex Saladrigas

      Don’t forget about adding a platform that low end phone users can actually use and enjoy!

      April 23rd, 2013 at 14:42

  12. Jef Spaleta

    hey, is there a status update on the store and whether there is phone stock left?

    If you are out of stock, can you perhaps take the “get yours” button off the front page? I don’t want to keep wasting time pinging the store front and getting the site is down message.

    I’m happy you’ve sold out, and I can wait to be notified via the newsletter mechanism as to expected availability for more stock (hint, hint-write a newsletter!) But the button on the main page leading to a store front that is inactive is just a frustrating tease now.


    April 25th, 2013 at 10:49

  13. Javier Agüera

    Dear Jef,

    Thanks for the tip. We will be updating our homepage soon with a message!

    We will be using Twitter to notify further coming of stock back online, please expect it to happen within 1 week time.

    Thanks for your support!

    April 25th, 2013 at 12:35

  14. Blake Davidson

    Any idea when they will be back in stock? Are you planning on doing a twitter announcement beforehand again? I’m super excited and hope it’s not too long before they are available again.


    April 27th, 2013 at 13:40

    1. Robert Nyman [Editor]

      Not sure when, unfortunately.
