Although already available on some HTC EVO 4Gs since yesterday, a new OTA update (version 4.53.651.1) is scheduled for widespread deployment over the next two weeks. This is a maintenance release that fixes issues with Picasa, Voice Recognition, and contact transfers over Bluetooth, along with some contact sorting and texting issues.
It is not known at this time whether this patch will break Revolutionary's recently released Gingerbread root method; however, as with all the previous OTA updates, it's better to expect that it will break root. So if you currently have root and want to keep it that way, then you should wait for a rooted version of the update to become available from one of the devs.
Those who want the OTA update as soon as possible can check for it manually through the usual Menu > Settings > System updates > HTC software update routin.
The new build is being rolled out in waves so Sprint's servers don't get completely slammed, which means that if it's not available to you now, it will be it later.
Anyone get it yet?[Android Central]
