"Jailbreaking" is a form of legal/illegal [depending on device] way of receiving "free stuff." For example: games, music, movies. You can also change the "theme" of your device, as if you could just rearrange everything like puzzle pieces and make them all fit. The most commonly "jailbroken" devices are the iPod Touch and the iPhone 4. "How to "jailbreak" them is a whole other long question.
There is only reason for why an iPhone needs to be jailbreak. The reason for a iPhone to be jailbreak would be for using the phone for a different service.
No, you can even unlock the iPhone when Jailbroken.
Your phone is probably an iPhone that is dis-acativated, in other word's you have no internet. You can still "jailbreak" it by removing you SIM card and "jailbreak" it on another iPhone that DOES and internet and just re-insert the SIM.
Yes you can. If it does not have a sim, you will be able to get one.
i dont know but u buy them ^^^ No you don't just go to jailbreakme.com Jailbreaking is a free service. If you have every had to pay for a jailbreak, you have been scammed.
You do not Jailbreak iTunes; you jailbreak iPods and iPhones.
You jailbreak the firmware.
Yes you can. there is a new jailbreak out called "spirit". Google it "spirit jailbreak"
Updating the iPod Touch software erases the jailbreak. You can update, but it will erase your jailbreak.
No. Your jailbreak will remain as it is. Syncing your iPod does not alter the jailbreak in any way.
Do what you originally did to jailbreak it in the first place.
