Hi all, wondering if anyone can help me with this. I've tried downloading iOS 5 the last 2 days on my iTunes, only problem is I'm still stuck in the dark ages running Tiger and iTunes 9.2.1 and whenever I try to get the new iPhone software it just says "the current version of iTunes 9.2.1 is the current one" and nothing else

Is there another site I could get the software from?? Will I ever be able to upgrade the software? Help!!

Many thanks.
