I don't know if this is related but there are quite a few (including me) experiencing the "Unable to join network xxxxxx".

This has been going for more than a month. What I found is that a network once joined that didn't offer proper connection, was the only network I could join. Forgetting this network fixed the problem but only for a day. The next day another similar network appeared that only had ip address and subnet mask. I knew this was similar to the network that caused the problem before, so I tried to press forget this network but there was no option. Now I'm stack and can't connect to my home router or wireless modem...

Iphone seems to hold these settings and stops from connecting to anything.

P.S: can you point me to a program that deletes these plist files so that iphone recreates them? And also write down some of them for reference to check if this solves my problem?

Thanks!
