Windows Phone 8 is upgradable according to Microsoft

"We will not have the same experience as we had when Windows Phone 7 was upgraded to Windows Phone 8," Greg Sullivan, Windows Phone director of public relations at Microsoft, said in an interview Wednesday at the International CES indicating that the next version of Windows Phone, which is expected to launch in spring 2014, will be backwards compatible with Windows Phone 8. It is expected that the next version will be called Windows Phone 8.1.

The statement refers to users of Windows Phone 7 being upset when Windows Phone 8 was released which could not run on Windows Phone 7 devices due to hardware restrictions.

Have fun!
