We’ve not yet independently confirmed this, but one of our Sprint connects just dropped us a line to let us know that Sprint is gearing up to push out a maintenance update for the HTC EVO 4G. Said to be targeted for June 28th, the fix is said to address three things:

  • Improvements to Wi-Fi performance
  • Exchange Active Sync improvements which include a fix to issue including new account set up, PIN policy usage, and Exchange Server 2010 Calendar Sync
  • Addresses Social Networking Sync issue with Facebook application which can improve battery performance

Thanks, S.!
