I don't know how to say it without sounding rude, but the sprint service on the iPhone 4s is simply awful... data is so slow, it frustrates me beyond words. I live in 60487 area code, near 183rd Street and 94th Avenue. I've heard all the promises of upgrading towers to 4G, but after only 7 months of dealing with it, I'm at the point of considering cancelling sprint service, paying the fee and getting a new phone with another carrier (since the 4s is locked to Sprint once it is activated, thanks a lot). That's how bad it is. Any help?
