Hello all. I am trying to decide between the two options. I have a SGS2 that I am planning to sell and have some extra cash. I was thinking if paying $375 for an iPhone 4 (16gb-locked) + $500 for an iPad2 (16gb/wifi only) for a total of $875 is better than paying $850 for an iPhone 4S (32GB/unlocked/includes tax). thanks.
