Fun with t-mobile
I setup my friends cellphone for wap via internet AP (as opposed to wap AP), because t-mobile charges ~10 times as much for wap as for internet. (Idiots; its same data underneath, and it costs them the same).
Anyway, in doing so, I modified his wap AP to be "newap" (or "no wap" in czech). Few days after that, he told me he had "interesting" call with t-mobile, where technical persons told him he is doing something very strange in their network. Apparently what happened is that they had "new ap" access point for testing, and he managed to connect to it ;-).
