Sprint just posted that an update is coming to the Evo 4G. It says that Version 3.29.651.5 shall contain fixes for calendar event edit issues and syncing of multiple gmail accounts, both of which have been subject of complaints for some time now.
But wait. There's more. Maybe. Word of the update actually started late last night at SDX Developers, and jerdog says that in addition to the gmail and calendar fixes, the infamous 30-frames-per-second graphics cap is lifted, and the GPS reboot will be addressed. We're hoping to get official word on those last two, but we'll gladly take the gmail and calendar fixes, too. [Sprint via Android Central Forums]
