Question on Music & Play:

Can I use a second-generation iPod touch with a wireless network protected using WPA or WEP?

Submitted by Reader

Answer:

Yes, the second-generation iPod touch will work with WEP-, WPA- and WPA2-secured wireless networks. For WPA in PSK mode, you should only need to key in the appropriate passphrase or hexadecimal string on the iPod touch to get onto the network.
