So I got my nice new 4s on Oct 14. Get pretty good reception everywhere but been dropping more calls at home the past few weeks, despite the fact that I'm in the darkest orange on AT&T's coverage map. So last night I give them a call to see what's up? I am a premier customer so I got their CS department and got the nicest guy. He offered me a microcell which is a mini cell tower that plugs in to your broadband internet. I asked what would be the cost of this and he said that if I put it on my card for $199 then he would credit my account. So a total of $224.93 was placed on my card and then this morning I see my AT&T account credited $248.23. So I basically got it for free, as I won't have to pay my phone bill for 2.5 months. I read so many people complaining about AT&T's customer service that it scared me to call but now I couldn't be happier. I will recommend AT&T to all my friends and family. Hopefully the iPhone 4s plays nice with AT&T's microcell. Anyone have any experience with the microcell please post. I am sure they are not perfect but I'd like to hear any experiences with one.
