iPhone Jailbreaking
How can I jailbreak iOS 6.1.3 / iOS 6.1.4?
Sadly for those with iOS devices running iOS 6.1.3 and 6.1.4 there is no jailbreak solution available at this time. Apple killed the untethered 6.1.2 jailbreak found at evasi0n.com with the iOS version 6.1.3 firmware update. The development team responsible for the jailbreak software known as the evad3rs has decided to wait unti the launch of iOS 7 before releasing the next untethered jailbreak.
Evad3rs Not Working on iOS 6.1.3 Jailbreak, Waiting for iOS 7
Evad3rs member pod2g has confirmed there will be no more jailbreaks for iOS 6. This means iPhone and iPad owners who would like to keep their devices jailbroken are stuck with iOS 6.1.2 until iOS 7 is released. This does not mean jailbreaking is dead like some Apple blogs are leading people to believe. Anyone who has previously jailbroken their device knows they will eventually get stuck using an older version of iOS. This is just how the process works.

Apple is expected to announce iOS 7 at its WWDC event sometime in June. While an official date has yet to be announced, some developers believe the event will be held on June 10-14th, based on a gap in in the Moscone Center calendar. It wouldn't make much sense for the evad3rs to jailbreak iOS 6.1.3 with the next big version looming right around the corner.
Apple to Patch Evasi0n Jailbreak With iOS 6.1.3
It may be sad news for those who are currently enjoying the iOS 6 jailbreak known as evasi0n. History shows that Apple always comes around with a response to the bugs exploited by the latest jailbreak, and this time is no exception. According to evad3rs team member planetbeing, Apple has already patched at least one of the bugs used by evasi0n in the first developer beta of iOS 6.1.3, making the jailbreak inoperable.

His comments appeared in Forbes, where he explained that not all hope is lost. The evad3rs have a stash of several other exploits they could use to put together a 6.1.3 jailbreak, however everything depends on how many bugs Apple fixes with the new firmware. In the meantime, those who have already jailbroken up to iOS 6.1.2 can continue to use Cydia as long as they don't upgrade.
How to Purchase / Install iOS Jailbreak Apps from Cydia
If you are new to iOS jailbreaking and want to know details about exactly how apps and tweaks are paid for, look no further. While the App Store is convenient and linked to a credit card through iTunes, you'll find that the jailbreak app store Cydia is just as convenient. Purchasing and installing third-party tweaks and apps to customize your iPhone, iPad or iPod touch has never been easier.

Once your iOS device is jailbroken with evasi0n you can begin to browse Cydia for interesting tweaks. When you're ready to install a package that requires payment, you'll see a Purchase button in the upper right hand corner. In the example below, the app CleverPin costs $1.99.
Evasi0n Jailbreak Updated to Support iOS 6.1.2
In case you missed the memo, iOS 6.1.2 does not patch the evasi0n jailbreak. Apple released iOS 6.1.2 on Tuesday to fix a Microsoft Exchange bug and some battery life issues. Evad3rs team member planetbeing tweeted that it was safe to download the new firmware, and iOS 6.1.2 has been added to the evasi0n website as a supported version.

Users are now free to download evasi0n on any device running iOS 6.1.2, but there is no need for iOS 6 users to upgrade unless your device is affected by the Microsoft Exchange bug. New jailbreakers can read our step-by-step evasi0n guide to help jailbreak any iOS device, including the iPhone 5 and iPad mini.
Give Yourself an App Intervention With AppCap [Jailbreak]
Are you spending too much time on your iPhone? Or are you addicted to a certain app? A new jailbreak tweak can help! Give yourself an app intervention by downloading AppCap. The jailbreak tweak allows you to limit your app usage by time of day, day of the week, or by frequency. Too bad it doesn't have a built-in breathalyzer to keep you from making stupid posts on Facebook and Twitter while drunk. That would probably me more helpful!

The tweak is free to download from the ModMyi repo in Cydia. Once installed, users can navigate to their Settings panel to set restrictions on how many times they can use an app. You can restrict your app usage by numbers of launches (up to 6), or by time of day to keep yourself from playing Angry Birds while at work. You can also avoid costly data overages by setting an app to only work when you're on Wi-Fi connection. There are two options on how to limit yourself; you can set up a pop-up reminder or have AppCap disable the launch altogether. Of course you can cheat by just turning AppCap off, but it might stop you from checking FlipBoard every 20-seconds.
Apple Releases iOS 6.1.1 to Fix iPhone 4S Bug, Doesn't Patch evasi0n Jailbreak
Apple has released iOS 6.1.1 to fix a bug only affecting iPhone 4S devices. The iOS 6.1.1 changelog simply reads: "This update fixes an issue that could impact cellular performance and reliability for iPhone 4S". The over the air update was only sent to iPhone 4S owners. The update comes after European carriers such as Vodafone, had to warn users not to update to iOS 6.1 because of "difficulty in connecting to the network to make or receive calls or texts or to connect to the Internet."

The good news is Apple did not patch the untethered evasi0n jailbreak in iOS 6.1.1. Planetbeing, one of the hackers who helped release evasi0n, tweeted that the jailbreak still works on iPhone 4S devices running iOS 6.1.1. Planetbeing added that the evad3ers will be releasing an updated version of the jailbreak which recognizes iOS 6.1.1 is supported.
Customize Your iPhone With These Popular Jailbreak Tweaks and Themes
Jailbreaking your iOS device allows you to modify your lock screen, home screen and even the appearance of your apps and how they are arranged. WinterBoard is a popular tool that allows you to alter the look of your device by downloading themes to your iPhone from Cydia. There are themes to change everything, including your lock screen slider, your iPhone keypad and even your Wi-Fi icon. WinterBoard offers so many more possibilities than just downloading drab wallpapers.

CustomSiriBackground lets you spice up Siri's boring look by giving her the background of your choice. There are also several WinterBoard themes which can change Siri's icon into something more fun. My favorite is Siri9000, which transforms Siri into HAL 9000 from the film 2001: A Space Odyssey. You can even change the Siri start up sound into a few Hal quotes with a little advanced jailbreaking know-how.
Must Have iOS 6 Jailbreak Tweaks: SwipeSelection
My personal favorite jailbreak tweak of 2012 was SwipeSelection, and it's compatible with the evasi0n iOS 6 jailbreak. SwipeSelection is one of those tweaks you have to use to truly appreciate. It's a simple tweak that makes texting, taking notes and writing emails on your iPhone or iPad a lot much easier.

SwipeSelection allows users to drag one or two fingers across the keyboard of an iOS device to move the typing cursor. This makes editing text much easier by eliminating the need to tap the display of your device to delete or change letters. You can use one finger for a more precise cursor drag, or two fingers to move faster across the screen. You can also easily delete or copy entire sentences by holding the shift key and dragging your finger over the text you want to highlight. This is all demonstrated in the original concept video from Daniel Hooper posted below.
Must Have iOS 6 Jailbreak Tweaks: Auxo
Looking for some great tweaks to get the most out of your iOS 6 jailbreak? Well if IntelliScreenX is Notification Center as it should be, then Auxo does the same for the app switcher. Auxo makes great improvements in the multitasking dock and takes advantage of the larger iPhone 5 display size.

The first thing you'll notice after installing Auxo is that each app in the switcher is displayed with a preview of its screen. Besides being aesthetically pleasing, these icons can be manipulated easily. Swipe one of the previews down and it's removed from the multitasking bar. Hold down on one and you will be prompted to remove all apps from the bar at once.
