If you're an iPhone user looking to crack through Apple's last update, which broke most known hacks, it would appear that your solution is near. Gadget Lab has more details, but it seems that Jailbreak is back in action thanks to a TIFF buffer overflow flaw.
However, that amounts to exploiting a security vulnerability, so you can expect Apple to patch it up (as it should) lickity split.
But there's another more promising rumor that Apple may be getting ready to announce third-party apps for the iPhone. Glenn Fleishman of Tidbits, a very reputable and long-standing Mac publication, reports that Apple may be on the verge of the an announcement regarding third-party apps.
Were it the average Apple site, I wouldn't be posting, but Tidbits doesn't normally traffic in rumors so I'll give them the benefit of the doubt. It's also interesting that Apple Insider (which does traffic in unsubstantiated rumors from suspect sources) says that Apple is collecting third-party application information for a directory listing on Apple.com.
Are the two related? It's hard to say, but if Apple really is as worried about apps disrupting the AT&T network as it claims (the way Apple paints it it sounds like a goatse jpg could take out the entire AT&T network), forcing apps to past tests and distributing them only through Apple's site is certainly one possibility.
Of course, it's also possible that the directory is just a collection of the web-based applications that have been built for the iPhone. Apple has said that it is working on a solution for developers to help them promote their web-based iPhone apps, but so far no details have been revealed.
