I have a LG Ally (Android powered) for about a yr now and its been decent. The screen never locks up or anything. The only complaint I have about mine is that it goes retarded sometimes. Anytime I upload a pic to fb from my phone it says space is low, and I have to erase something off it, even tho I have a sd card.

I have heard good things about the casio commando. Might wanna look into those. They look neat as hell
