I think we all generally assumed this, but it's nice to see Apple going on record as saying they'll patch the PDF font exploit that currently allows Jailbreakme.com -- and potentially any malicious hacker out there -- to run code on an iPhone with just the tap of a web button. CNET scored the quote from an Apple spokeswoman:
"We're aware of this reported issue, we have already developed a fix and it will be available to customers in an upcoming software update."
That might not be great news for Jailbreakers in the waiting, but this is a really bad security vulnerability and Jailbreak or no Jailbreak, Apple needs to fix it as soon as possible. Apple of course currently only provides updates in the form of complete firmware re-writes, which means we're likely going to have to wait for an iOS 4.0.2 (and hopefully a proximity sensor fix), or iOS 4.1 this fall when Apple introduces iPod touch 4.
If they could somehow work out a way to patch iOS, especially OTA, without having to wait until an entirely new firmware is ready it would go a long way towards speeding up their security response time for situations such as this.
