Looks like EVO Shift 4G owners won't have to wait till tomorrow to get their Gingerbread fix; in spite of what we heard yesterday, it appears that the update is already available.
As a refresher, the update brings Swype and addresses a few media streaming-related bugs in addition to adding all the usual Gingerbread goodies.
To download it to your device, first open the Settings app, then tap "System Updates," and finally go to "HTC Software Update." Alternatively, you could wait for Monday, when Sprint will officially begin the rollout, automatic notifications and all.
Feel free to leave a comment about what it's like to be liberated from the shackles of Froyo at long last!
