Hi, I have a ipod touch 2G 3.0 jailbroken and my sister just got a new ipod touch 2G 3.0 but the only difference is hers is not jailbroken. When standing in the same location in our house, her ipod has full bars when connected to the same wifi access point meanwhile mine only has one bar. What could be causing this? Is it the fact that hers is not jailbroken? Or maybe has apple upgraded the wifi chip in the ipod for a later model? It doesn't make sense.
