Gevey Sim sells a SIM card that can be hooked-up with your existing SIM card thereby unlocking your AT&T locked iPhone for use with T-Mobile and other cell carriers. I bought a Gevey card from Hong-Kong trough ebay (about $30 incl. shipping). It was easy to install. However, the Gevey tray appeared to have a manufacturing flaw. Once installed I couldn't get to open the tray. I ended up removing the iPhone's mother board to get the darn thing out. But to credit Gevey, the card did work (unlocked the AT&T phone). In hind side I should have gone with a software unlock instead of Gevey....See critical reviews
