Apple iOS 4.3.4 security fix jailbroken overnight

Apple’s iOS 4.3.4 PDF vulnerability fix issued Friday didn’t stymie jailbreakers for long -- a beta jailbreak tool for the mobile software update was released on Saturday

Apple’s iOS 4.3.4 PDF vulnerability fix issued Friday didn’t stymie jailbreakers for long -- a beta jailbreak tool for the mobile software update was released on Saturday.

However, the iPhone Dev Team warned that most jailbreakers should just stick with iOS 4.3.3 instead of rushing to use the latest jailbreak tool. The iPhone Dev Team’s MuscleNerd tweeted: “redsn0w b3 http://is.gd/6eek4Y is a *tethered* 4.3.4 JB for kernel hackers only (see #3). Most should stay back at 4.3.3!” 

In other words, you’ll lose your iPhone hack if you boot up your device without having it tethered to a computer.

MORE APPLE: Inside iOS 5.0 

In issuing the iOS 4.3.4 software update on Friday, Apple said that the security flaws could have resulted in “an unexpected application termination or arbitrary code execution” and “malicious code running as the user to gain system privileges.”

SlashGear and other Apple watchers warned that Apple looks to be making life more difficult in general for those who want to jailbreak, or mess around with the insides of their iPhones and other mobile Apple devices: “[T]he road ahead for iOS jailbreakers looks to be trickier than ever. iOS 4.3.4 reportedly also closed off [two] other loopholes hackers had been using for untethered solutions – an integer overflow-related bug and an incomplete code signing issue. Meanwhile, iOS 5 will reportedly block firmware downgrades using a new signing system.”

EverythingiCafe’s Tim Barribeau comments that he suspects even if the jailbreaking community comes up with an untethered jailbreak it might be best off holding out at this point until iOS 5 comes along in the fall.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
