I've been twice and used different iPhones. Here are pics with 3gs: http://imgur.com/a/3epbh Here are pics with 4: http://imgur.com/a/VCGEP This year, I'm trying to decide whether to get a camera. I wouldn't get an expensive one. I have an iPhone 4s this year. My question is, what would be the best option? Get one of these two cameras or stay with the 4s? I'm particularly concerned about getting good pictures in the shows which tend to be low light. Thanks!
