Okay so in my apartment the wifi saturation is crazy. My old iPhone 4 was able to connect to channel 14 for wifi stock, but the 4S refuses to even acknowledge the router. Right now I'm using ch 13; while it works, channel 14 would be better since it doesn't overlap with 1-13 at all. They say a picture is worth a 1000 words, so here's a picture showing how saturated the US channels are here:
Anyway, I assume this iPhone is following some kind of regulatory restrictions and disabling Ch 14 (though it's weird that 13 works). Is there anything I can do to reenable it now that we have a jailbreak?
