Well, it seems like Apple has gone and posted an iPhone 1.0.1 update (mostly security fixes, although some people are reporting stability and speed improvements too), as well as a Safari 3.0.3 beta update (will fiddle around with this on Windows, where Safari has become my main browser) and a Mac OS X security update.
Interesting to notice that the WebKit issue descriptions across these are fairly similar (for example, CVE-2007-3944 is quoted in all of them, and it’s not the only one), which is sure to get the speculation regarding shared codebases for iPhone Safari and desktop Safari rolling again in earnest.
Update: Safari still can’t figure out how to maximize to full screen on a Windows secondary display, though.
