Hello, Im about to get an iPhone 5 but Im into this situation... 16 or 32 gb. Im going to get the iphone with a second line under my att account and cancel that line after a month. That way I safe a few dollars from buying it at full price. The 16GB model is $199 so it sounds good but is the 16Gb model enough?... I dont have a lot of apps and photos but you know... Would I end up needing more?
