Boy do these Android Users move fast. We have news that the T-Mobile G1 has been jailbroken. Meaning full system access and read and write capabilities have been obtained. We have yet to try the method but its supposed to be quite easy.

Here are the basic steps (via modmygphone):

  1. Turn on WiFi in the G1 (Settings > Wireless Controls > Wi-Fi). Make sure you're connected to a network.
  2. Start up PTerminal (search in the Market) and you'll get a prompt once its launched.
  3. Enter cd system and hit Enter.
  4. Enter cd bin and hit Enter.
  5. Enter telnetd and hit Enter. You've now started telnet on your G1.
  6. Enter netstat and hit Enter. You'll now see your G1's IP address. You can also find this in the Settings > Wireless Controls > Wi-Fi > and click on your network you're connected to. It will show you your IP.
  7. Start up Terminal on your OS X machine, or bring up a command prompt on your Windows box. Type telnet[your.ip.address.we.just.found] and hit Enter/Return. So, if your IP was, you'd type telnet and hit Enter/Return.
  8. You are logged in as root now. To remount the system file as read write, type mount -oremount,rw/dev/block/mtdblock3/system from the Terminal/Command Prompt and hit Enter/Return.

This method will obviously be for those eager to explore the inner workings of your G1. But if you still want to jailbreak but aren't so confident in your hackerish talents, the G1 jailbreakers are expecting more major breakthroughs on the jailbreaking front. Check this space for updates!
