Some questions about the Ipod Touch

I have an iPod Touch and some questions, a little loose, so here they are:

• Is it possible to share applications between different iPods?
• How can I go back to firmware 1.1.4? I tried several times without success ...
• Is it in 1.1.4, there are many applications when jailbreak the iPod?
• In Tap Tap Revenge (1 or 2) or tap Tap Dance, can use his own songs (in the manner of Tap Tap Revolution, if I remember correctly, who was on 1.1.4)?
• Finally is it that it is better to be jailbroken 1.1.4 or 2.2 (jailbroken or not)?

Thank you in advanc

Why return to the 1.1.4 firmware when the 2.xx branch is fully operational?
The Jailbreak for iPod allows you to have a good batch of app, the App Store already has a lot (20 + 000) ...

What do you mean, "share applications?

2. Download the 1.1.4 firmware and select it when you want to restore your iPod in iTunes.

3. There are many applications, but not very interesting. They are all free unlike the AppStore.

4.

5. It's up to you to see, compare the two and you take the most stable and provides the applications you want to use.
