Just like the reported EVO 4G update Monday, the EVO Shift 4G now has a Gingerbread update available for manual download. An OTA for this update will not start until June 27th, and as always an alternate option is avialable for those impatient users. To grab the update simply go to your home screen and hit “Menu” then navigate to Settings > System Updates > HTC Software, which will start the process. Among the features of the new update are Android 2.3.3 Gingerbread, HTC Sense UI 2.1, Swype, a new quick setting stab in the notification bar and a slew of performance and aesthetic enhancements. The download will be rather large so have a WiFi connection or 4G ready when you attempt it. Be sure to let us know how it goes for you.
