Although AT&T appears to have stopped selling the Samsung Epix smartphone – it no longer appears as an available option on the Shop section of their web site – a Windows Mobile 6.5 update for the Messenger class handset has been released.
The update flashes the ROM of the Epix with an updated version of the Windows Mobile Professional operating system.
The updater file along with installation instructions can be found here.
Remember that ROM updates clear a smartphone’s memory and return it to factory specs, so be sure to sync and backup your data before performing the update.
