Apple has released iOS 4.3.4 (iOS 4.2.9 for users on Verizon) which fixes a vulnerability with the operating system’s PDF support that could enable attacks via maliciously-crafted PDF files. Earlier this month, Jailbreakme.com relaunched using this PDF exploit to enable user to jailbreak their iOS devices. As expected, the patch shuts down that particular jailbreaking technique.

The update is free for the iPhone (3GS or newer), iPad, and iPod touch (third and fourth generations).

The PDF exploit was also the subject of a consumer alert issued by Germany’s Federal Office for Information Security warning users of iOS devices to stay clear of PDF files from unknown senders. Although there are no known cases of the PDF exploit being used maliciously in the wild, security experts warned the technique could quickly be exploited for malicious purposes.

The update is available via users’ iTunes applications.

We're just days away from Apple's Worldwide Developers Conference (WWDC 2024), which means we're about to get our first look at iOS 18. The new iPhone operating system is expected to get RCS texting in the iMessage app, more customization options for the home screen, and maybe a significant design change overall. Now comes word that changes will be made to the native Mail app.

According to AppleInsider, the Mail app is about to undergo a significant transformation. It's getting a powerful new search tool, Smart Replies, automatic sorting for different email types, and more. But the real excitement lies in the app's expected integration of AI functionality, a feature becoming a hallmark of iOS 18.

AT&T just made it a lot easier to upgrade your phone

Do you want to upgrade your phone more than once a year? What about three times a year? Are you on AT&T? If you answered yes to those questions, then AT&T’s new “Next Up Anytime” early upgrade program is made for you. With this add-on, you’ll be able to upgrade your phone three times a year for just $10 extra every month. It will be available starting July 16.

Currently, AT&T has its “Next Up” add-on, which has been available for the past several years. This program costs $6 extra per month and lets you upgrade by trading in your existing phone after at least half of it is paid off. But the new Next Up Anytime option gives you some more flexibility.
