I'm looking for a smart phone that's 4G and is capable of playing some decent 3D games. I remember a friend of mine having one with an awesome first person shooter but I forgot what it was even called and lost contact with him. If someone has knowledge on whats out there let me know.

Also I wanna develop apps on a phone but the only thing I'm aware of is Microsoft Visual Studio Express Edition For Windows Phone. Are there any others? Thanks in advance.
