one you get unlocked (just plain easy to do) you can download and CDMA rom and flash as you do a stock rom no difference in the flashing process. Its easy as pie my freind!

Then just grab a rom from the upgread section of the TP2 CDMA thread and start flashing but becarefull it becomes a addiction!!!
