yep, same thing happened with me with my iPhone AFTER i paid the 30.00 to upgrade to Snow Leopard. Apple is supposed to make these things easy, i'm EXTREMELY frustrated I have to install a large package of s/w (developer tools) that i wil never use so i can restore a function i once enjoyed under 10.5. i fought with the cell company for 45 minutes to have them charge me additional money just for the privilege of tethering my phone, it worked before i upgraded, then the one day i take the laptop to school, the wifi doesnt work, i try to use MY OWN internet, only to find out that bluetooth has been crippled. Apple is supposed to make things dependable. Not pleased with this one, Apple.
