I have Windows Vista 64 bit. I can't download Itunes 8. Very frustrating, because I can't update my Iphone until I have Itunes 8. I have tried deleting everything, but the Mobile software refusing to be deleted. With just Itunes 7.7 removed, I still can't download 8.0. Any suggestions. I created a killer Led Zeppellin ringtone and can't wait to get it on my phone. Thanks.
