Chosen Solution
I have not been able to receive wireless on my iPhone 3GS. I have done all the troubleshooting I could find on the Internet, worked with Apple support via phone and finally visited a store and a Genius checked out the phone. He said it was a hardware failure problem and that I would need to pay $199 to replace the phone. A tech savvy friend pointed me to this site. What a find. Anyway, 1. Is there a definitive way to test to see if there’s a hardware problem and 2. If there is a hardware problem is it something I may be able to fix myself? Thx a million!! Update It seems that your response was cut off (…Proper hot-air rework station and liquid flux) or I don’t understand what ‘proper hot-air rework tation and liqid flux’ means. Will you respond to this? Is it somethin I should/could do?
if you have very good soldering skills you could do what chappers suggests — resolder with a hot air solder station and liquid flux.(his answer wasn’t cut off) or you could take it to the local phone repairman and ask him to do the work. the wifi chip is the large silver rectangle on the back right of motherboard in pictures. iPhone 3GS Teardown (step 12 it is the long rectangle on top edge of this picture) you can also find this part for sale on ebay.
