Think this is a bad SIM chip or somehow T-Mobile needs to change some network registration settings? At least I know my E61 settings are correct.
Just out of interest, what network is your friend on? If he's on T-mobile too then you've almost certainly just got a bad SIM card.

Whatever the case, I guess the next step would be to ask T-mobile for a replacement SIM card (I assume you can get one free?) and see if that works. If it does, you know it was a bad SIM chip, if it doesn't then it's probably some kind of compatibility issue possibly at T-mobile's end.
