Um, I think I'm having some problem with my Ipod Touch wifi. Mine is a 3g ipod 8Gb OS 4.0 and is jailbreaked. The problem is my wifi signals are fluctuating. When i surf with Safari, I suddenly get a disconnection and this is annoying me a lot. Before when i used OS 3.1.3, the wifi signals were fine but after I updated to os 4.0 i'm getting these problems. Oh btw, I also use a laptop but the wifi works just fine with it so I don't think there's any particular problem with the wifi itself. Do any of you guys have similar problems with me? or perhaps any solutions?
