It seems to happen randomly, sometimes very rarely and sometimes (like today) every 2 minutes. I'll try to open Safari or something and then a box will pop up asking me my wifi password (it hasn't changed ever). I'll put it in and it will work fine, and then randomly again it will ask me for the password. Anyone know why it's not saving the password permanently? It's a real pain having to retype that password and I shouldn't have to. Ipod Touch 3G 32GB, latest 3.1 update.
