I am sure something new in one of the roms will come up but man i feel your last few roms are good enough to call it a day
*EDIT*
two things,
I am probably pulling the trigger on the TP2. So i hope to see you on the flip side, Assuming i get the courage to shell out the cash, and second. If i keep my mogul without any plan, it should continue to work with tomtom right in offline mode? pick up a gps signal etc. I am not exactly sure how assisted gps works or if its need for the mogul to pick up a signal.
