You may have heard the rumor and conjecture about Android supporting multi-touch in the not-too-distant future. Well, if you are a brave soul and are willing to gain root access on your beloved Android T-Mobile G1 device, then multi-touch may be ready for you sooner than you think.
Although still in the proof-of-concept phase, some ingenious people in the development community have provided an unofficial hack for multi-touch, including multi-touch browser and, as seen in the video, a multi-touch map app. If you are feeling adventurous and have an idea of what you are doing, then try it at your own risk. If you don't even know what "root access" means, then you may want to sit this one out and wait for official multi-touch.
