yeah, shoudn't have skipped out on the sprint customizations, i believe that is was "routes" things to your TF3D... but yeah... ur gunna have to hard reset sometime or another... you should flash a juicy rom, those are REAL awesome! Read up on unlocking and flashing... i'd get outta the oem sprint rom asap, you can download sprint tv and picmail cab files, so its all good...
if you don't like wasting time setting things up over again, this thread will be helpful
