According to
HTC EVO Maintenance Releases site the update seems to only update the following:
Includes enhancements/fixes in 4.22.651.2
Corrects the following introduced in 4.22.651.2
- voicemail notification issue
- hearing aid compatibility menu disappearing
- Netflix compatibility
Which I didnt not have an issues with any of these. 1) Never have the VM isseus. 2) Dont wear a hearing aid soe I would never of know that there was an issue with this. 3) I dont use Netflix.
If this is the case, then alot of the other reported issues ( which I did have issues with) got overlooked... Lets hope for the best though...
