Not sure what 're-setup the modem' means, but you shouldn't have to do that either.
since OS4.2 only recognizes max 4GB micro card and 4.2 was when I formatted the microcard, I wondered if when on 4.5 which does recognize up to 8GBMC that I would have to format the MC again after install of 4.5
re-setup the modem,,, here I meant the phone it self, operating as a modem for my PC, I just got it set up with the help of the tmobile bb support tech and wondered if that had to be done over again after install,,
