I have a 1G iPod Touch. I decided to buy the 3.0 update from Apple... now I regret it. I live in an apartment complex, and my old laptop detects about 15 different networks at full or near full strength. My iPod on 2.2.1 also detected as many, and I could connect to my home network with full bars downstairs (which my laptop can still do fine). Once I install 3.0, 2 networks show up total with 1 bar (neither of them are even my home...). So I tried getting closer, and I LITERALLY had to be within a 5 feet radius of my router to get a signal (any longer and nothing connects). I decided to go back to 2.2.1. After a lot of trouble doing that, I succeeded but the range is still nearly dead and showed no improvement at all. Did 3.0 fry my wi-fi chip!?
