I'm wondering if anyone else has noticed a lack of sensitivity and inablility to connect to some wifi hotspots after ugrading to 3.0. I have a 2G Ipod Touch and use it alot in a work environment with multiple access points spread over a large area. Immediately following the upgrade I noticed that I was no longer able to connect to several "marginal" access points. results with those access points had been consistantly good over a period of time. So, it appearsthat the wifi radio may have been tweaked in the new firmware version. I'm considering a downgrade to 2.1 just to test this theory if indeed that is possible. Has anyone else had a similiar experience?
