Ipod no longer detects Wifi anywhere

Hey all I joined because my ipod's wifi stopped working completley it had been jailbroken for like a year or more and worked fine but one day it just didnt detect wifi anymore. it was right after i used a freinds black berry as a wifi hub to check something on the internet. after that the thing didnt seem to work or soon after that. I re set all the settings on the ipod Nothing is wrong with my Network i keep a close eye on my wifi network and my parents network as well. I have another ipod touch that was long ago damaged beyond repair but it has the antenna in it Im very tempted to try an antenna swap and see if that doesnt fix the problem because since i re set the ipod back to original im pretty sure its not a software problem . Any one else had this problem?

no ideas???

When you say you "reset all the settings on the iPod", does that mean you deleted all networks that may have been saved from previous connections? Sometimes it is just trying to connect to too many unavailable networks and all you have to do is clear that list.

Report back if issue still persists. Network/wi-fi issues are a sticky situation.
