So I've had my iPhone 4 since Sept and I have had to replace my SIM card 2x and my phone and I still have no bars everywhere I go. It's not Apple their product works great it's just AT&T is horrible. I live in a booming city with AT&T stores everywhere and when I walk in all of their phones have full bars, my wife's iPhone 4 even has full bars but for me I never get bars. I walk into stores next to Apple stores and the AT&T stores and nothing. AT&T told me to get the 3G Microcell and I responded "So because your service sucks horribly for everyone you want to charge us even more for this device to give me bars in my home (which again wife, brother, family all have full bars) because my phone can't? It seems AT&T should be giving these things away since they know their service sucks horribly thus the reason for creating this device. I'd write AT&T but I for some reason can't find their e-mail address so tomorrow I will call. Thoughts?
