During the Windows Phone 7 era, many users were extremely disappointed when the new system was not compatible with their existing devices. Now, as the Windows Phone 8.1 system is about to arrive, quite a few people are worried that current Windows Phone 8 devices won't be able to upgrade to version 8.1. Some media outlets have also speculated, suggesting that WP8 phones might not be upgradable to WP8.1.
Although this is just speculation, it has still caused an uproar in public opinion. To the point where some developers even remarked, "If WP8 cannot be upgraded to WP8.1, it wouldn't surprise me at all," showing a sense of resignation.
In order to calm everyone's concerns, an official Microsoft spokesperson reiterated that all Windows Phone 8 phones will be upgradable to the Windows Phone 8.1 system. This news should put WP8 users' minds at ease.
