The T-Mobile G1 may be a lot of things, but one thing it isn't is multi-touch capable. So, if you want to enable multi-touch on the first ever Android-based phone, you’ll have resort to some firmware hacking.
The video below shows how the hack works fairly well in maps and the internet browser. Granted that it’s still in its infancy, don’t expect it to work on all of the Android apps just yet, but we are looking forward to further developments in this area down the road.
The full details on how to go about this procedure can be found here, but do exercise caution as this is hardly authorized by T-Mobile. With that being said, if you’re brave enough to give this hack a go, do give us a shout out below in the comments if it is indeed a hack worth trying. We’d certainly love to hear your two cents on it.
