Jailbreaking your iOS device allows you unlimited access to apps, unapproved by Apple software and much more. Once you've jailbroken your device there's plenty of fun things you can do with it. Try some of these apps and tweaks.

biteSMS

With biteSMS, you can improve the text messaging experience on the iPhone. There's the ability to use scheduled messages, the ability to delay messages, quick reply and quick compose and many more.

The free version of biteSMS has ads but if you want to spring for the pay-version, it will cost $7.99

iCaughtU Pro

It would be devistating if your device was ever stolen. Thanks to Find my iPhone, Apple can try to help you locate your device, but what if the culprit simply turns off your phone?

With the iCaughtU Pro tweak, iPhone robbers won't be able to switch the phone off. It also snaps a picture of the robber who tries to turn off the device or enters an incorrect passcode. It will then e-mail you with the location of your phone. 

For only $2.50, this tweak could save you from getting your phone stolen.

F.lux

This tweak is especially useful for those who use their phones before bed or have ever been awaken to an alert on their phone late at night. Instead of the blinding brightness that normally occurs when you interact with your device late at night, F.lux adjusts to the time of day and turns down the brightness to save your eyes a little.

F.lux is a free tweak and available here.

TetherMe

This app turns your device into a personal hotspot. You can then use your mobile's internet connection on your computer or other devices. This is especially useful when you're traveling and can't find free Wi-Fi. A one-time fee of $4.99 gives you access to unlimited TetherMe service.

BatterySafe

Save battery with this nice tweak. When your iPhone gets low on battery, BatterySafe will automatically disable heavy-power sucking features like Wi-Fi, cellular data, Bluetooth and GPS. 

BatterySafe is a free tweak and it's available here.
