Review: Motorola Photon 4G
The phone application itself is a stock Android calling tool. In-call features are unaltered from stock Android, and are simple to use.
The contact application is the stock Android app, which is kind of disappointing. I mean, it's all-powerful and socially connected and stuff, but there aren't any cool contacts/favorites widgets, such as the one on the Droid 3 (for Verizon). It's the same old, boring contact application. Sure, it integrates with Twitter and Facebook, and lets you store a bazillion contacts and their too-many email addresses, but there's no fun involved.
