A new firmware for the late Pocket Edge showed up on MobileRead a few days ago. I read about it at the time but I didn't want to post about it until I knew that it worked. There's at least 1 report that it does.
Warning: This is a hacked firmware. It's entirely unauthorized and it might kill your Edge. It will also void the manufacturer's warranty. Well, you don't have one anymore so I suppose that doesn't matter.
This update brings you a newer version of Android, and it also has the standard Google apps including the Android Market. It's not clear that all the apps work properly, but this firmware seems to be stable. Now would be a good time to update.
