I currently have 2.2.1 firmware and just jailbroked that version on my 1g. It was working fine Sunday morning but when I tried to use it Sunday evening I kept getting a "cannot connect to server" error when I tried to connect to anything on the internet. My touch is connected to my network because I see it listed and also the settings show a valid network IP (192.168.1.101). I've even reset my router a couple times as I found that sometimes fixes connection issues but that did not work. Any ideas????
