Are you an Android developer looking to test your apps on multiple GSM networks? Are you anyone else, simply looking for an unlocked HTC G1? In either case, Google and T-Mobile will apparently be happy to hook you up. A special “developer version” of the G1 is now available from T-Mobile 100% SIM and hardware-unlocked. Woo! The handset can be purchased from T-Mobile’s G1 site and shipping within the US is free. It is also available to be shipped internationally to 18 different regions. There is a catch of course but it’s hardly a big one. Since the unlocked G1 is intended for developers, you will have to register on the Android Market site and pay a one-time registration fee of $25. That brings the grand total of this fully-authorized unlocked G1 to $424 shipped. Yeah, we’ll take it.
