We had a US import 8GB 1st Gen iPhone when they first came out. Currently running 1.1.3 firmware. Have been tempted to move up to 1.1.4 but now with 2.0 I think I'll wait. Using Orange PAYG sim
Best phone I've ever seen, didn't have a video recorder but now there are a couple of apps out that do this well. We have a hard case on ours that clips over the front and back and sticky screen protectors that we change about every 3 months.
