After reading through 36 pages on the New Sprint 6.5 ROM thread, I'm sticking with Plutonium. I'll flash the radio update, but I've just gotten too used to Vin's superior ROMs to go back to a stock Sprint ROM.
Vin, you've spoiled us all with the quality and features of your ROMs.
One question, though: Anyone have any luck getting Block Recognizer to work on the Plutonium ROM? I've enabled the CLSID registry entries, and installed RHO09076.cab, still no dice. I cut my PDA teeth with the original Palm Pilot, then went to the HTC Touch, then the Touch Pro, now the Touch Pro 2, and just find it easier to write directly on the screen than to use the keyboard. Old habits die hard.
