I'm still looking for a used iPhone 5s, and i come across the 64gb version here and there. Is there any good reason why the 64gb was disco'd? Was there a problem with it? or even just minor issues the 16 or 32gb ones didn't have? I see you can still buy brand new 16 and 32's in the stores. Also, is there any real need for that much storage on a phone? Does anyone actually use up that much gb, on a phone? Just wondering if its worth it to pay a bit extra for one should i come across a decent deal... or just stick to the more common 16 or 32gb ones.
