Friends of mine are moving from the UK to Ann Arbor, Michigan in a couple of weeks. They plan on getting new iPhones -- but are having a bit of trouble. It appears they were told at the very last minute they need a U.S. credit card first. Anyone else here move from the U.K. (or elsewhere) to the States, and had trouble getting an AT&T account? My friends were hoping to have iPhones immediately upon arrival, but realize now it could take a while. Anyone know how long it would take them to get a U.S. credit card? (I haven't owned a credit card myself in over a decade, and don't know anything about them anymore). Also....anyone happen to know what AT&T service is like in Ann Arbor?? Thanks in advance to anyone who has answers!
