Hi guys, I may sound stupid....but can anyone please explain how the whole wifi thing works on ipod touch? I got mine a few months ago, and still haven't looked into that matter. I don't have a wireless connection on my pc, does that mean i won't be able to connect to a network on ipod when at home? Also, the wifi menu does show a connection established (with a tick against the name) but pages don't load on safari.its just confusing.And finally, does wifi need to be connected to receive and send mails?? thanks.
