I just thought that there should be a thread for the hardware and software we have set up with our i760's.

sync & charge cable
screen protector
was using TomTom GPS receiver (Freedom 2000 keychain on the way)
cheap-o autozone phone holder for vents (I've been blasting heat from other vents)

iGuidance v3.0
SBC Pocket plus (made it iPhone-like)
SBCH Weather plus
