Hi and welcome to the Forum.
Doing some searches is the best way to answer your questions, if then you cant find what you are looking for then by all means post your question, there are many friendly and informed members here only too willing to help you.
As for Jailbreaking check it out here http://www.ipadforums.net/ipad-hacking/
And, if I may add - any/all legitimate jail breaks are free. If you see anyone offering up a jail break for a price, run, because it's probably a scam.
To my knowledge, there is currently a scam offered by Ghost for ios5, they charge for it.
I hope you find this forum as informative and addictive as I do!
You will find that there are many members with a great knowledge base, waiting to help you with any issue you might have.
