ugh it sucks, man i know i am waiting for one as well,, i have sent you an emal to a hacked version of it.. from what it seems like al lot of people have been able to install it and run it with no problems! but apple should already release it dammit..
so since the 3.0 version i had for few hours was hacked i decided to downgrade to 2.2.1 and updrage from itunes to 3.0 since its out.. The hacked version was basically a real version 3.0 that leaked out onto torrent sites.. i am currently upgrading 3.0 from Itunes so i wont have any problems down the road when MMS comes out!
alot of nice upgrades... but still no flash in safari ><; i'll get mine updated in a few days. re organizing my music library and d/l-ing abum art, atm
