Well the old backing on my iphone 3g(16gb) had a huge disgusting gash in the back and part of the inside was exposed so I decided it was time to do something about it. As I bought it from my friend it has no warranty so I ordered a replacement backing from ecaseshop.com. At first I did have problems with the buttons, now it's only the home button that is a little messed up. But now that I've got most of it back to normal the wifi is weak. The wifi is extremely weak, it will work when I'm really close to the router but not even a few yards away. 1)Could the new case be blocking the signal more? 2)Or could I have loosened something when replacing the case? 3)Also does anyone know where the wifi part of the Iphone is located so that I might be able to take a look on the inside again? ------------------double post merged------------------EDIT: ok small update. After a bit more of fiddling I tightened a few screws in the iPhone and the wifi has a greater range than it did before, I'm am in another room on another level of the house and it is working. Also it's on firmware 3.0.1 would a firmware upgrade help? I know some people have said that 3.0 is buggy when it comes to wifi. Oh and also I got the power button fixed so it doesn't turn itself on and off anymore =D.
