With RedSn0w there is the option (when jailbreaking) to add multitasking and a homescreen wallpaper.
If you have Cydia then there is no point to re jailbreak. If you try to re jailbreak, The tool you try to use will not let you jailbreak it because the Cydia sources are already installed into your device.
It already is for a long time
No, because it will just get rid of the jailbreak. Plus, there isn't another jailbreak yet for iOS 6 anyways, so i wouldn't if i were you.
Redsn0w jailbreak 6.1.3 for the iPod 4G is already available. It was released in March 2013. However, if you use Ultrasn0w to unlock your iPod do not update 6.1.3.
If you have already successfully completed the jailbreak, then just turn it on as you normally would.
It has already been released, the jailbreak provider is called redsn0w.
There are many places that one could obtain wallpapers featuring racing cars. One great source would be to seek out already made wallpapers from online websites such as 1000Wallpapers or AutoWallpapers. If one can't find what they are looking for there, it is very easy to take a photo and turn it into a wallpaper yourself.
N-O-P-E
Yeah of course. It isn't going to make a difference. When you jailbreak your IPod you are going to add an app called Cydia. Which take it from there will give you all the things you can dream of. :D
yes, since it is already jail-broken it wont run the risk of being bricked or broken. i am doing this right now and my ipod is completely fine.
Yes. You wii can be repaired so that you can be able to update or get apps even though your son tried to jailbreak it.
jailbreak your ipod using blackra1n.com (the easiest fastest and safest way to jailbreak) then down load the Cydia app off of the blackra1n app and apply the theme using Winter board, which will automatically install after using Cydia. Note: blackra1n works with ipod touch firmware 3.1.2, if you already upgraded your firmware to 3.1.3, downgrade your ipod's firmware to 3.1.2 Also, if you already have 3.1.3, you can jailbreak with a new software called Spirit, which is just as fast and reliable.
