I upgraded and unlocked my iPhone 2G to OS 3.0 and since then seen bluetooth and wifi issues. The wifi doesn't see any networks at all. As I am on T-Mo network with no 3G band support from iPhone, I am a total dependent on WiFi.
When I go to the WiFi Networks in settings, I see "Choose a Network" and it tries to find a network but cannot. I don't see anything under that. I tried searching for networks in the same place where I used my 2.2 firmware both at home and office but looks like the phone doesn't see them at all.
The other issue was with my bluetooth headset. It was working great with my 2.2 firmware and once I upgraded to 3.0, it connects but nothing comes out of it.
I installed the firmware according to these instructions:
iClarified - iPhone - How to Unlock/Jailbreak Your iPhone 2G on OS 3.0 Using RedSn0w (Windows)
and I restored my iPhone with the backup that I took before installing 3.0 firmware. I reset the network connections, reset the phone itself but nothing solved my wifi problem. Anybody has similar issues? I decided to go back to 2.2 but before pulling the trigger, I thought I will post it here.
Any help is appreciated.
