The
iPhone 2.2.1 update just hit, and it promises to fix various Safari, Mail
and Camera bugs. It applies to iPhone and iPhone 3G (no iPod Touch yet), and
doesn't seem like it introduces new features. We're installing and looking into
it for more info. The update is 245.7 MB, in case you're on dial-up at your
grandma's house. Jailbreakers should hold off on installing until it's confirmed
that 2.2.1 can be jailbroken, and unlockers should definitely hold on.
