HI,

I have 16gb iPHone 3Gs with 3.1.2 jail broken and unlocked. Up untill few days wifi was working but now it is not working. Can some one pls suggest what is that I need to do?

I have reboot the phone and I have manually try to join my home network but still no luck.

Appreciate a help, if you have ran in to this situation before.

Thanks,
BJ
