Well, actually Fring works...... a little bit. Very poor quality. You better step out the door and shout out loud to whoever you want to contact. On a clear day you might even see them.
The apps that should work with a camera don't work on the eDGe (because of Android 1.6?)
The 'barcode for apps' scanning doesn't work.
So far I didn't find any use for the camera given it's position.
BUT, always look on the bright side.... maybe Froyo makes things better. Soon in this theater.
