The requirements for the iPhone 3G list iTunes 7.7 as a requirement.
I sincerely hope that it is a release that provides some fixes rather than just an upgrade to support the new phone.
For as long as I can remember now, iTunes hasn’t closed properly and I have to kill it’s process from task manager. And as of a couple of days ago, it won’t start up at all! I really need to get onto fixing that….. or rather, Apple do; Lots of people experience this problem when using the iPhone / iPod touch apparently….
Edit: have now fixed iTunes *touches wood* well, at least it opens; for the last two attempts it has closed properly too! I hope it continues. Was something to do with Symantec i.e. Norton’s LiveUpdate service (which I had disabled)…. Will have to investigate that link when I can.
