Here is a list of what the author says are bugs in Jelly Bean on the EVO LTE.
"most of the issues have been Sprint’s."
"There are rumors coming up from the stores than an update is coming soon to fix many of the bugs, but as far as I know there’s no official timeframe on that and that leaves many non-root users out for weeks with buggy equipment"
Yeah, I heard that yesterday too. The 16th is the end of the 30day period. Something happens before then on March 12 or 14th... can't remember what. I'm trying to find info on it... where are you seeing it? My normal sources are turning up empty. Do you think they'll still "close" on April 1st?
