Thanks to MultiCleaner iPhone users no longer have to manually quit each application running in the iOS multitasking dock to free up RAM and improve performance. Not only does the $0.99 jailbreak tweak make it possible to set up custom Activator triggers to quit all apps, it offers customization for multitasking dock behavior.

Apps can be pinned to the left side of the multitasking bar for quick access, and app icons can be rearranged within the multitasking bar. When apps are not running but have been recently opened, the icon appears darkened, while actively running background apps are normally displayed.

MyAssistant is one of the more popular jailbreak tweaks that allows you to do all kinds of great things like change Siri's background and create custom conversations. Co-creator Andrea Oliva announced on Monday that the tweak will be receiving an update to add even more features and a few bug fixes.

Version 1.1 will give Siri the ability to download, open apps easier and send tweets. Most of these functions are available for Siri via other jailbreak tweaks, but MyAssistant delivers them all plus more for the low price of $0.99. Check out the complete list of changes and fixes below.

You can now make your iPhone even more lively with the new jailbreak tweak iSounds. The iSounds app allows you to apply sound effects to your iOS interface. Once downloaded and installed you can choose from themes like Deadspace, Mac OS 9 and Windows XP. Your iPhone will then make a sound every time you open an app, boot your device, or change the volume. The iSounds "combiner" allows you to apply different sounds to different actions like deleting an app, opening a folder and so on.

A new jailbreak tweak called Swipe For Mail makes reading multiple emails as easy as swiping your finger. Once installed the tweak allows you to navigate through your emails by swiping left or right instead of hitting the up or down arrows. The original method of sifting through your inbox isn't that difficult, but a lot of iPhone owners prefer swiping gestures to tapping buttons.

Hoping for a waterproof iPhone 5 later this summer? A recent patent uncovered by AppleInsider could mean that Apple is throwing cold water on the concept. New immersion detection sensors are described that would more accurately determine when a device was damaged by water.

Current Liquid Submersion Indicators found on Apple products simply turn red after they come into contact with water. This has caused problems as even a high level of humidity can sometimes trigger the indicator to turn a different color. The patent describes an improved method that would use water-soluble glue.
