Apple Releases iOS Patch to Fix PDF Vulnerability

By Ian Bell Published August 11, 2010

Apple has just released the latest update for iOS 4.0.x (iPhone, iPod touch) and iOS 3.2.x (iPad). Previous versions of the mobile operating systems had a PDF vulnerability that was exploited by the iPhone Dev Team to jailbreak the devices.

The iPhone Dev Team was able to make an incredibly simple jailbreak (for the end user) that simply required users to visit the website JailbreakMe.com to jailbreak their devices. The jailbreak was followed up by a software unlock which allowed the iPhone 4 to be used on other GSM networks (in the case of U.S. customers, T-Mobile).

With this security update, that loophole is obviously closed, so the ball is back in the iPhone Dev Team’s court to find another iOS security hole to expose.

The best free VPNs for 2026

The best free VPNs still come with compromises, but a few offer enough privacy and flexibility to be genuinely useful.

A virtual private network (VPN) encrypts your internet traffic and routes it through a server run by the VPN provider. Websites see the VPN server’s IP address instead of yours, and you can get around geo-blocks, censorship, and ISP throttling. The best VPN services are paid, but there are still a handful of free options that do the job well.

Most free VPNs come with a hidden cost, because running servers isn’t cheap and a company that doesn’t charge you has to make its money somewhere else. Many do so by logging your browsing activity and selling it to advertisers, while others flood you with ads and track you across apps.

The best Kindle in 2026: Here are the top Kindles for reading

From a pocket-friendly e-reader to a premium color notebook, Amazon has a Kindle for almost every kind of reader.

There's nothing quite like curling up with a good book on a cold evening. As much as I love the feel of a physical book, books take up a lot of space, and carrying more than one on a trip quickly becomes a chore. That's where e-readers come in, and the Amazon Kindle remains one of the best options.

Amazon just refreshed its Kindle lineup with thinner, lighter designs, a new flush-front display, and colors that wrap from front to back. Add the Kindle Scribe and the Kindle Scribe Colorsoft to the mix, and you have more choices than ever before.
