If you are an existing user of Windows Phone mobile operating system-powered device, you must be eagerly waiting for the official release of the forthcoming mobile operating system - Windows Phone 8. Reports are making round that Microsoft Corporation might not be making the upcoming Windows Phone 8 available for existing Windows Phone users.
In other words, Windows Phone 8 – codenamed ‘Apollo’ – will not be coming to current Windows Phone handsets, which include Nokia Lumia series, HTC Radar, HTC Titan, and Samsung Omnia W. So, if you are on Windows Phone 7.5 (also called Mango), you are more likely to be stuck on Mango only.
Even Microsoft is not making it clear whether the existing Windows Phone handsets shall be upgradable to Windows Phone 8 OS or not.
Therefore, if you are thinking of buying a Windows Phone-powered handset, it is recommended to just wait till the end of this year for a Windows Phone 8 handset instead of risking being stuck on the older Windows Phone 7.5.
