iPhone 3GS Replaced dock assembly wifi good but very weak GSM Edge 3G
My phone had a small crack on the back plastic where the dock connector is located. I tried to super glue, unfortunately glue crept into dock connector to the point my phone would not charge. I followed your online guide and was very careful (didn't force anything) and replaced the microphone/speaker/antenna assembly part. While putting it back together I lost 3 screws, which is the only potential problem I can find with my iPhone 3GS.
WiFi works great as do all other features other than mobile phone and data service. I do get a weak (one or two bars) AT&T service and 3G when I'm in dense metropolitan areas.
Any ideas what could be wrong? Could three screws really cause such a huge loss of signal?
Is this a good question?
