My iPhone 3G’s bak housing is soooooooooo scratched up! I wanna replace it! I found a white one (with the tabs on the bottom) from eBay for 8 bucks! Are they any good or will it be sh**?
I think this is one of those questions that is hard to answer. Some of it is of course personal preference. The other thing that I would do, make sure that the seller is a reputable seller. Check the feedback of the seller, check the return policy. I have had very good results with most of the vendors (yes even the Chinese ones) when it comes to fit and quality. I purchase most of my iPod repair parts from the ebay vendors and have not had any issues. Good Luck
