EDIT: I now have unlimited Will tethering work even though at&t will try and charge for it? What kind of apps are so amazing that you should do it? EDIT: Is there a jb app that would allow me to save login info for my uni's wifi network? It's the kind of thing where you load a page on safari and are redirected, not a direct pass on accessing the network. So I have to enter it every time...a jb would be worth it it to fix this.
