Got a T-Mobile G1 and incensed that you can't run multi-touch on it? Well now you can.
While Apple has threatened to flex its legal muscle against anyone that steals their IP (to borrow Tim Cook's words), it's possible to enable multi-touch today on an Android device simply by rolling back to firmware RC29 and installing a bunch of hacks called JesusFreke.
Although multi-touch isn't officially available for Android-based handsets like the T-Mobile G1, you can enable it and a bunch of other features by following instructions posted here. For obvious reasons this technique isn't for the faint of heart and a full backup is required.
After rolling back to RC29, it's just a matter of installing a telnet client and JesusFreke V1.4 which is basically Android with a bunch of hacks installed that allow you to run multi-touch, tethering, and even a task manager. The G1 multi-touch hack, courtesy of Lukehutch still has some bugs and isn't nearly as smooth as the iPhone but it's a step in the right direction for Androids.
Now, if Google would only release it.
And while we're at it, the G1 desparately needs the virtual keyboard seen in the Cupcake developer branch too.
