Hello guys I'm new to these forums. I have a iPod Touch 2G 8GB (MC Model) with 0S 4.0. It has been previously jailbroken with Spirit at 0S 3.1.3 and later was updated to 4.0. After getting 4.0, I encounter wifi problem over and over. I connect to my home based Linksys router and few minutes the connection drops. I tried the wifi network on laptop and everything works fine. Please help because internet is one of the main purpose in the iPod Touch!
