Boost Mobile users with the Motorola i776 get a ‘phone not suported’ error when trying to install the Gmail Mobile app. Here’s a workaround to get you set up with Gmail Mobile 1.5.
After you get it installed and running, setup one of your hotkeys to point to Gmail by going to Settings/Personalize. This way you don’t have to run it from the Java Apps screen. This package may also work on some of the other Motorola iden phones…if so post a comment!
There is also Gmail Mobile 2.0, and though it will install on the i776, it will not run.
