hi, started to develope the ipjone 5 sleep\lock button problem, at the minute its not working when you press on the right jand side of it, press on the left hand side and it will lock the phone, been reading online and looks like its quite a common problem, from reading it looks like you need to replace a ribbon cable that goes to lock button and volumes buttons, pretty much have to gut the iphone 5 to get to it, has anyone had this problem and fixed ? ive replaced a few screens on iphone 3gs and iphone 4\4s but never messed with a iphone 5, so not sure yet whats best thing to do, if anyone has had this and fixed it or no anyone who can ? thanks
