I know that MSU has a contract with Verizon and the coverage is generally excellent, I'm looking though for people's experiences with AT&T/Cingular on campus and in the surrounding area. It's been a while since we've had this conversation and I'm sure things have changed considerably. (and no, I wouldn't switch for an iPhone). If you have AT&T coverage experience anywhere else in Michigan, I'd like to hear from you too.
