HTC released source code for the myTouch 4G, G2, and DROID Incredible - HTC Source
HTC has always been pretty good at releasing their source code for their Android phones in a timely fashion, so it’s nice to see them continue the trend by releasing the source code for the myTouch 4G, and the latest updates for the DROID Incredible and the T-Mobile G2. We know developers have already pulled system bumps from all three of these handsets, but an official code release should make things a little easier to work with. The HTC source code releases typically don’t have much impact on the day-to-day users, but it’s always helpful for the development community which likes to push their handsets to the very limit with system tweaks and customized ROMs.
