Hey folks, I have an iPhone 3g, and it's LONG past time to upgrade... Frankly, I'm less than satisfied with AT&T, but I have a contract through my employer that's pretty good. Any recommendations? How are Sprint and Verizon? Before I went to AT&T, I had a Sprint phone and was pretty happy with it. What about for international use? I travel, and need something that will work overseas. I know I can use AT&T, but can I swap the SIM for a local network? If not, I'll probably jailbreak the iPhone 3 and use that overseas. PLEASE hit me up if you have experience and recommendations in that area!
