I tried two hardware sim unlocks neither of which worked. Finally, I got a gevey-3g sim card which unlocked my iphone 3g version 2.1 Everything appears to work very well. The instructions which came with the sim unlocker said "make sure that you turn off your iphone before inserting GEVEY-3G sim. And also do not use airplane mode in any time." Not using airplane mode is a small price to pay for an unlocked iphone! BTW, I unlocked to the T-Mobile network. Gevey sim purchased through eBay.
