I know a lot of you that say wifi keeps itself on, even when your touch is sleeping, But I noticed that mine does not. Everytime I turn it back on, I have no signal, and have to wait for a signal. I did jailbreak my touch, so i notice that I have to wait like 3 seconds for Wifi to activate, before I can use weather or mail. I was just wondering if this was the same case for others, as I don't know if this is a bad thing or a good thing. It's kind of annoying waiting for Wifi to turn on, but then again...people here like to complain about battery life.
