iPhone 3G iOS 4.1 Speed Fix Confirmed

Many iPhone 3G owners have complained of poor performance and other issues after installing iOS 4 on their devices. The new operating system limits features such as multitasking on the older hardware to keep an acceptable level of performance. Unfortunately something went wrong and Apple has been investigating why iOS 4 brought so many iPhone 3G units to a crawl.

Fortunately, the company is poised to release iOS 4.1, a major update that's already in beta 3 with developers. Joel Evans over at ZDNet has confirmed a vast improvement in iPhone 3G performance with the iOS 4.1 firmware update. In fact, he reports that some functions on the iPhone 3G are faster with iOS 4.1 that they were using 3.1.3. This is welcome news for iPhone 3G owners, whose problems were overshadowed by reception issues on the iPhone 4 antenna.

Why Should I Update my iPhone Firmware to iOS 4.0.2?

Apple has released a security fix for iOS 4 and users now have to decide whether or not to install the update. There are pros and cons to installing the update, mostly revolving around whether or not you're interested in jailbreaking your device. The security problem was first discovered and used by the Dev-Team to hack iOS 4 and provide a simple way to jailbreak through the Safari browser.

Now that Apple has released a fix, the developer responsible for the JailbreakMe 2.0 in-browser jailbreak software has made the source code of his exploit public. Let's be clear, the iOS 4.0.2 update will make jailbreaking with JailbreakMe 2.0 impossible, however now that the source code of the jailbreak is public, security threats are bound to multiply.

Apple Completes iPhone Browser Security Fix

Apple has already developed a patch for the iOS 4 Mobile Safari exploit revealed by JailbreakMe. The security hole affects all iPhones, whether they are jailbroken or not. Malicious code could possibly take over the iPhone and steal personal information by taking advantage of weaknesses in the PDF display code built into Safari.

Currently, the only known software to take advantage of the exploit is the JailbreakMe 2.0 application, which loads itself into the iPhone via Safari and jailbreaks the device. The procedure has been described as brilliant and also scary by security experts who have been studying the inner workings of the code.
