Hey guys, I will be travelling to the US in July and will stay till august. My question is this. Will the iPhone 4 or 5 be available unlocked in the US by then. As far as I know it is only available on 2 carriers in the US i.e AT&T and verizon. So is there any possibility of getting an unlocked iPhone in the US. Besides that, if i want to purchase an iPhone 5(it will be released by then), will it be hard to get? I hear there is a lack of availability of the iPhones around the first 2 months of launch. Thanks.
