iphone 3g & 3GSWed 01 July 2009
I don't know if it works but there is a way to unlock tethering on AT&T in the US and other countries.
clickity with your iph0ne.
I see this as a big security issue with iphone/safari software. sure there is an "install warning" when you open the file, but since when should a browser on any platform be able to trigger opening a registry file or a plist file?
