I've seen many broken screen/broken panel/not working properly iphones, then i thought, is repairing iphones/ipods/ipads profitable ? i saw guides on a website, with pictures and tips and everything required to repair a device, unfortunately, my brother broke his LCD screen withought braking the outer glass in his Sony Xperia J. so i searched for an iphone 4/4s with a broken screen/not working properly, i've found an iphone 4 with a working LCD screen but camera isn't working. what do you think ? should i buy it ? note: they want about 87$ for it, its ther lowest price i could find, i think its pretty much low. also, i have found an OEM camera replacement for 5$. what do you think ?
