Adding Themes is only available to Jail broken, iPod Touch, and iPhone users.

Yes you can, but expect some iOS functionalities that are on, say the iPhone 5S won't carry over to the iPhone 4.
Yes. Just sync your iPhone with your computer and download the 2.2 software. The new software should wipe out the jailbreak, so just re-install it.
Jail-breaking an iPhone is illegal, but jail-breaking an iPod Touch is not.
NO you MUST have a Laptop Or a Computer
under settings switch to auto instead of T-Mobile. It worked for me, and I'm running 2.1 firmware, unlocked and jail-broken!
yes jailbreaking your Iphone/Itouch will not ever break the devices. the only difference with jailbroken iphone is that you have access to "Cydia" which is an app store made for apps that are not allowed on the Apple App store. I highley suggest using GreenP0isen.
No, that is not true. Jail broken iPhones still have access to the Apple app store. The only thing it will do is break your Apple warranty on your iPhone.
