..I recommend sticking w/ an Apple product. Keeps things much easier since the Apple ecosystem is so tight (aside from the fact that iTunes is a bloated goat). Either the 4 or 4S will likely suffice. Since you want improved camera performance, definitely the 4S. 4G is a moot point since you are on ATT's network and LTE is not completely built out yet, and HSPA+ on the 4S is really good, although technically only '4G Lite'.
