Well you could always load up spb backup and make a FULL backup, that way you can restore your phone using the ZeroSense flash.
Esentially with using ZeroSense +spb FULL restore it would be like you never tried anyother roms. Thats what I do for my wife now that I test my new roms.
Ultralite+Sense has EVERYTHING working in HTC messaging (even has facebook integration). Its a lot leaner than ZeroSense, but remember its still a test. My wife is using it and she seems to like it. so give it a try. Oh and the long Send key is mapped to the Comm manager =)
Thanks, I'll try ultralite+sense next. I've used SPB backup before, but the reason I wouldn't this time is the phone has gotten a little flaky - a fresh start is called for. Now, I just need some time off to flash.
