I currently have an iPhone 4 on AT&T. I barely get any service in my home which is why I have a microcell. As I'm sure most of you have read the microcell is far from reliable. So I'm wondering if anyone knows if/when the AT&T 4g network is finished if I should expect more reliable coverage in my home using that generation iPhone on the 4g network? I know Verizon's coverage is good since I have a friend with the Verizon iPhone and she has no signal problems in my house. I'm now contemplating switching over to Verizon to get onto an unlimited data plan then upgrade to their 4g iPhone when I'm eligible.
