Well it seems that after less the 2 weeks the open source G-Phone has been jailbroken.  I am not to sure what is so exciting about it since it is open source but they what do I know.  I haven’t played with one yet.  But with the ability to jailbreak I am looking forward to getting my hands on an unlocked one.  I took these directions from modmygphone.com.

“Well, it didn’t take too long. G1 is jailbroken. Full system access, read and write, has been obtained. And this method is quite easy. A few folks at the xda-developers forum discovered you can start telnet on the device by downloading PTerminal from Android Market, and then you can telnet to the device from your computer.

Once you’ve done that – you’re logged in as root. One simple command mounts the system dir as writable, and away we go.

Here’s the basic process:

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 192.168.1.101, you’d type telnet 192.168.1.101 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 opens a whole world of possibilities.” (poetic_folly).

If I ever get around to picking up a G-Phone I will write my own how-to guide.
