Quick update... I too have had alot of success. The Alltel ROM started giving quirky probs like missing text alerts and such (probably something I installed on top of it) So I have flashed a few things now. I finally settled on OMJ's 6.1 verizon2 ROM. REALLY happy with it so far things have been stable for about a week now with all my crap loaded. For the record I am using the .35 Radio with the updated GPS drivers. I have installed a bunch of mortscripts and am using AstroGPSlauncher with TomTom and its all working great -- avg time to get satellites is about 2-5 minutes if not shorter. Pretty stable all said.
Has anyone tried the New leaked Sprint ROM?
Also someone leaked the the HTC Diamond SIP! It looks silly (See below). I am not sure if it is considered WAREZ so I wont post a link but a good google search may turn something up.
