Apple’s latest iOS 4 update dropped yesterday, which “fixes a security vulnerability with certificate validation.” Jailbreakers were initially advised not to update to the latest firmware, but as long as you’re happy with a tethered jailbreak for the foreseeable future, you’re safe to go ahead and update your device and then jailbreak with the latest RedSn0w release.

Apple released its promised iOS 4.3.4 software towards the end of last week to fix a security vulnerability in mobile Safari that made the latest JailbreakMe exploit possible. It goes without saying, then, that updating your device will eliminate the possibility of jailbreaking with JailbreakMe, but it will also kill all other untethered jailbreaks too!

Apple may have just released iOS 5 Beta 3 today, but the Dev Team never rests, and the beta has already been jailbroken using the popular tool, RedSn0w. The mouse hasn’t exactly gotten the cat by the tail this time around, though. If you jailbreak iOS 5 Beta 3, prepare to give up all of your third-party App Store apps as punishment.

Apple released iOS 4.3.3 on Tuesday to address the infamous location tracking issues with the iPhone. To our surprise, however, the update to does prevent the latest untethered jailbreak solution, leaving 4.3.3 still vulnerable to the hack.

Dev-Team member C0mex posted a message on Twitter yesterday that confirmed the exploit was still successful. While we don’t recommend you try jailbreaking the latest iOS release with Redsn0w or PwnageTool, it’s only a matter of time before both tools are updated.

In its fight against the jailbreak community, Apple usually fixes the vulnerabilities that make the latest jailbreaks possible, forcing hackers to find another exploit. The fact that it hasn’t with the latest iOS release is evidence that Apple rushed to get the 4.3.3 software out and quickly quash the location tracking bugs, putting an end to the whole ‘Locationgate’ saga.

We’ll keep you updated on the iOS 4.3.3 jailbreak as it progresses.

Shortly after the release of iOS 4.3.2 yesterday, hackers discovered that the firmware update can be jailbroken successfully with the latest version of Redsn0w and PwnageTool bundles. These are, however, tethered jailbreaks – which means you’ll need to connect your device to your computer every time you need to reboot.

Though it’s possible to jailbreak the latest iOS release, it is still a good idea to stay away from the update for the time being if jailbreaking your device is important to you. There is yet to be an announcement from the Dev-Team regarding a jailbreak for this firmware, and there’s a chance you may lose your untethered jailbreak completely if you upgrade.

If you’ve jailbroken your device for the first time this week (thanks to the iOS 4.3.1 untethered jailbreak being released), chances are that you may not know where to begin. There are thousands of neat things that you can do once jailbroken.

This post will cover just 6 of them, all of which I personally consider “must-have” tweaks for anybody who has recently joined the jailbreak scene.

Kevin Lee, a senior at George Mason University, Virginia, has turned iPhone jailbreaking into a full-time job, hacking customers devices to earn an impressive $50,000 a year. Lee uses Craigslist to advertise his services, which include unlocking, jailbreaking, and customizing devices to a user’s preference.

Lee told The Washington Post that he started off with a mere 5 to 10 customers a week – most of whom were friends. Now he pulls in between 30 and 40 – performing relatively simple hacks that many people don’t like to attempt themselves. A recent customer from the Mongolian embassy wanted his device unlocked so that he could use it in Mongolia when he moves.

Lee’s interview with The Washington Post is rather short, and he has since declined to provide further comment, removing his advert and contact details from Craigslist.

On Sunday an untethered jailbreak for devices running iOS 4.3.1 was finally released by the Dev-Team in the shape of PwnageTool and redsn0w. However, early jailbreakers are reporting that the exploit is causing issues with Wi-Fi on their devices.

I0n1c – aka Stefan Esser – is the brains behind the jailbreak, and confirmed the problem in a tweet earlier today. However, it seems users are only experiencing the issue with certain routers.

Been holding out for redsn0w before jailbreaking your iOS 4.1 device. Good news: the Dev Ream has just released the latest version which will allow you to jailbreak your iPhone 4, 3GS, 3G, 3rd or 4th generation iPod Touch and second generation AppleTV on either Mac or Windows machines. It uses geohot’s limera1n exploit, and also adds “custom bootlogos for iPhone3G/iPhone3GS/iPod2G users (with qualifying bootroms)” and an option that implements the ‘DFU’ button in PwnageTool” in Windows.

Interested? Grab it here, and let the hacking commence.
