Well, it seems that the T-Mobile G1 has been successfully unlocked for use with other carrier SIM cards. All things considered this unlocking method has come pretty quickly, and it seems to be a really easy process.
The unlock process is as simple as entering a code, and the codes are being offered for $23.99 through Unlock-TMobileG1.com. Just visit their website and submit your payment and your IMEI number, which is done through PayPal and then sit back and wait for your unlock code to be delivered via email.
Then once you receive the code, just insert another non-T-Mobile SIM and then enter your unlock code when prompted. Once the code is entered, hit unlock and assuming the code was entered correctly you should quickly see a message that reads “Network Unlock Successful.”
After that enjoy your G1 on just about any carrier your choose. Of course, as with any unlocked phone, some network settings may need to be adjusted once the handset is unlocked.
