Whenever the G1 vs iPhone debate gets underway, iPhone purists are quick to flag the G1′s lack of multi-touch input support. Turns out, it might just be able to handle it after all -on the hardware end, at least. Whilst tearing his G1′s workings apart line-by-line, a crafty coder going by RyeBrye came across an interesting artifact. It seems the driver for the Synaptics touchscreen has some code commented out; after recompiling the kernel with said code back in, he was able to track two finger presses at once.
So if the hardware supports it, why no multi-touch on the G1? Patents, presumably. While this in no way actually enables to you to do any kind of multi-touch funnin’ immediately (nothing made for the G1 is currently coded for use with multi-touch, afterall), it’s certainly a step in the right direction. Though we probably won’t see any official support for multi-touch on the G1 any time soon, someone with a bit of spare time to tinker will probably figure out a way to make use of it before too long.
