so I lost my iphone 5c whilst out drunk, first phone ive ever lost, gutted, was in perfect condition and working order, didnt have any insurance on it so have to buy a new phone myself, thinking about getting a 2nd hand iphone 5s off ebay instead of going for a new 6 as its pretty much half price, how long do you think this model will be supported in terms of updates? I have no other phone so really need to get something asap
