Hi longtime reader, but first post. I have iPhone 3G and original iPhone. Original iphone is being used with no service just on wifi as a ipod touch. Wifi is working fine on Powerbook and iPhone 3G, but all of a sudden after 1+ year it is no longer working at all. It doesn't even see my home network when right next to router. I have seen other posts of same problem over past month on apple.com and there are no answers and I hadn't seen issues posted here yet. Has anyone had to deal with this issue? Anyway to fix it? Thanks!
