iPhone 3GS ios 6.1 wifi issues
I have factory unlocked iphone 3gs, ios 6.1, modem firmware 05.16.08. Before upgrading to ios 6.1 the iphone wifi was working like a charm. but after the update, the wifi signals are really very weak. When i go near a router like literally under the router, i can connect to the wifi. when i move away few steps the signals disappear. I am really worried as i have been to mnay websites, but there is no solution. Mostly say it is ios bug buttt i think that there is a possibility that the wifi antenna might be faulty or weak. I am really thinking to change the wifi antenna but i am very worried that after repairing, the phone might get some new issues. it is not opened so far never repaired. I love my phone. Apple's support is not available in my country. Please suggest.
