Iphone 3g Mainboard Damage?
I have an iphone 3g 16gb the last friday the iphone start shutdown with the battery full of charge the only way for turn on back is conecting to the charge cable. I leave the iphone on a repair store because i dont have waranty and they tell me the mainboard is damage, and say he have a replacement for $150.00 he say me that the serial number will be the same no change. I think he is a liar and want to sealth $150 because i think if he replace the mainboar the serial will change too. Somebody can confirm this?
