Windows Phone 8 (codenamed Apollo) is the next generation of Windows Phone, as officially confirmed by MS at an MSDN seminar in August 2011 and previewed at Microsoft's 'sneak peek' at Windows Phone on June 20, 2012. Devices will be launched by four companies, Nokia, Huawei, Samsung and HTC and others include Acer Lenovo and ZTE. All devices will be based on System on Chips from Qualcomm (Snapdragon S4 Plus). Current Windows Phone 7.x devices will not be able to run or update to Windows Phone 8 and new applications compiled specifically for Windows Phone 8 will not be made available for Windows Phone 7.x devices.[29]

The GDR3/Update 3 update is possible to install on any Windows Phone with GDR2 by registering for a free Microsoft App Studio ID,[30] installing the certificate sent by email (not necessary) and lastly installing the Preview for Developers app[31] before checking for updates in the settings menu on Windows Phone. However, this may void the OEM and carrier warranty of the device.
