I got ahold of a 3.0 beta firmware 2 for my iPhone 2G and updated. It was a pain, but I finally got it to work. Everything worked just fine, except that I lost use of my wifi. My network will show up every once in awhile, but when I click on it, it usually won't connect and if it does, it just disconnects a couple seconds later. I downgraded back to 2.2.1 assuming this would fix the wifi problem, but it's still there. I have done everything I can think of to fix this, but nothing has worked. I rest network settings, and even downgraded to 1.1.4 so I could downgrade the baseband (thinking that might have been affected with the 3.0 firwmare) and then restored to 2.2.1. Still nothing. I NEED HELP!!
