I have an 8gb iphone with the latest firmware. At home I have a strong wireless network, to which the phone has always connected immediately. For the last three mornings, when I unlock the phone and take a look at my emails, the phone has used the gprs/edge connection, as though it has not recognised the presence of wireless. I go to the wireless settings and my network is there but not connected. I connect to the network (no need to enter the password, it remembers it). Then if I sleep the phone and unlock it, the network is found! But the next morning the process repeats!! Am I being visited in the night by the network fairy?
