I just tried to sign up for AT&T personal rewards, but from what I can decipher from their site you MUST have AT&T residential long distance to participate (I called them to confirm this) and you forfeit all your points if you leave AT&T residential service and do not switch back within 60 days. Also, you can only have this offer, OR the BA 5 miles per dollar on your residential line. Since AT&T rewards pays only 1 Starwood point per $ = 1mile this isn't as good as the BA deal, and the BA deal is nowhere near as good as current offers from Sprint and MCI. So it's hard to justify having a line with AT&T at this point just to get 1 mile per dollar spent on wireless unless you have really big wireless bills.

The only useful thing I could figure out about this is that some of the language on the AT&T terms and conditions seems to say that if you had residential AND wireless service on a combined bill, then you'd still be eligible even if you dropped the residential service. But the CS rep denied this. She didn't seem too well informed though--didn't even know you could get BA miles from AT&T, etc.
