I have an iphone and use at&t.
I have no complaints with at&t… as much as I hate how big they are(monopoly)… my plan is good I have rollover minutes out the ass and the global coverage is great and not overly expensive. I used to have a blackberry with at&t and i really had no complaints. I think they have the best service. Other than that verizon is the second biggest in terms of coverage then sprint then tmobile.
