Here’s a friendly neighborhood tip for the latest iPhone 3.1.3 update – DON’T DO IT!
I ran the update an have had no wifi more than 10 feet from my router ever since. GPS is shot as well. I’ve stumbled upon some reports of the same bit want to do my part in spreading the word. Hopefully this will be resolved soon, but it’s been an eternity since I’ve had a decent iPhone. Good grief, Apple.
