How good is a iPhone 4 for taking pictures at concerts?

Could wireless channel be causing computer to freeze?

I recently changed the wireless channel on my Uverse router to channel 1 because the default channel had too much interference.

I have an Alienware PC and compaq laptop that connect to the network as well as a Wii and two iPhones.

The Alienware computer is hardwired into the modem.
