I don't know that AT&T ever really quit sending out letters for free microcells, but if they did, they're at it again. I received a letter in the mail yesterday saying I just need to go pick mine up, so I'm going to get it later today. I'm still a little bit confused about what criteria they're using to select who gets these for no cost though. I have pretty decent service inside my house (3 or 4 bars normally). The only reason I can come up with is because I have two iPhone 4s on my account that aren't in contract. I was an AT&T customer previously, but my current account has only been open a few months. Anyone else receive a letter recently?
