Ok...thank you vry mch... :) Aftr insurance I will jailbreak it.. Can I use call function using cellular network or send messages using cellular network like normal mobile after jailbreaking it....?

Thank you Mickey330 for quick reply...I got 1 more question....I have insurance for iPad. After un-jailbreaking if my iPad damages and if I take iPad to the store where I have bought insurance, will they replace the iPad successfully..? or due to jailbraking insurance is cancelled...? and what...

I have iPad Air 2.(updated to 8.1.2). I want to jailbreak it. I want to ask that if i jailbreak it, it will void its warranty. But if I unjailbreak it again then is there any chance that apple will come to know that I have jailbroken it in the past....?
