I tried At&t with the iPhone but I was getting my voicemail days late yup DAYS late unbelievable and forget about text.
I also had t-mobile when it was Voicestream and it was the worst thing ever. People would call me but someone else phone line would ring LOL cheap stuff.
Sprint/Verizon hands down. they roam of each others network and the coverage is amazing.
