Thanks for the replys
I have checked my mobile and it is not locked to specific network. I did investigate the "hotspot" option but there is no cover in the area Im gonna be spending most my time, so that is going to be out the question. I have checked on the T-mobile USA website and can confirm that there is GPRS coverage, but what I can't find out is if I was to purchase a Pay as you go package weather it supports GPRS. Now in the UK I know it does. But I have a feeling things are a lot tighter in the states.
As I believe the Americans want to be able to track all their internet traffic/usage/abuse. I think that the Pay as you go will be blocked, as anyone could walk into Walmart, purchase a simand pone pay as you go deal for $30 and have the ability to access the web. Where as if they tied it down to contracts only, they would have all the users details and all internet activity would be trackable.
This is only a guess, just wondered if anyone could confirm.
So the 1st thing I would parobably need to know is if a US Pay as you go Sim will support GPRS.
