For those of you in St. Maarten with unlocked iPhones, TelCell is providing GPRS for free to pre-paid customers. For some weird reason they wouldn't provide me the setup info over the phone so I had to go down to their offices to speak with a tech and he entered the info into my iPhone. He was totally unimpressed that someone was actually using an unlocked iPhone on TelCell. He was desperately clutching his Sony Ericsson phone the whole time... not sure what that was about. He seemed to think is was some sort of iPhone killer. Anyway, for those of you with TelCell in St. Maarten:

It's not very fast... but so far it has worked everywhere I've been on the island.
