I live in the US and have a AT&T connection. I had a Nokia 6102i initially with them, with the data plan. I ordered a e71 through Amazon.com (unlocked, obviously). I then inserted the SIM card from the 6102i to the e71, and everything worked. The data rate is 3.5G where I live, and is absolutely awesome. Now, can I order this n900, and if I just remove the SIM from my e71 and insert it into my n900, will it continue to work? Same speed?
