We’re fans of pinch-zooming and that means multitouch. Although the interface is natively supported by both the hardware and operating systems of the Nexus One and Droid phones, it is locked out of the stock installation. You can make multitouch work on both handsets if you’re willing to do a little firmware alteration.
The coding has already been done for you, it’s a matter of loading a custom kernel. Both the Nexus One and the Droid have been rooted, and that’s what you’ll need to do to unlock multitouch with new firmware. In addition to gaining full access to the device OS, you’ll need to load up some different apps that support pinch zooming, etc. Luckily, these are readily available and you may like them better than the stock browser, maps, and photo applications.
