hello, i recently did cydia upgrades on my gf's 3G using wifi and when I rebooted, the wifi couldnt find any network. She hasnt updated cydia in a couple months since she lives in a dorm. is this a normal occurance in which upgrading cydia stops the wifi from finding any network? I have a 3gs and havent had any problems. upgraded to 4.0.1 and upgraded cydia as well. thanks in advance for any help.
