I was looking to jailbreak my iPad but I'm worried about a few things... Before my iPad, I had a 2nd and 3rd generation itouch, which I jail broke using black rain. The jailbreak went well for the first 3 months.. Then suddenly it shuts off (I was not out of battery) and when I try to turn it back on it shows the plug into iTunes sign... So I plugged it into iTunes and nothing happened... Then I tried to restore it and I finished the restoration process then I try it and has the plug in iTunes sign again.. I try restoring again and same thing happened.. I ran blackrain again and still nothing.. So I just said what the hell and got an iPad 16gb.. So now, even though ive had bad experiences I want to jailbreak it for free apps because I've spent too much money on iTunes money.. So my question is, will anything like that happen to an iPad? And if not what jailbreak software should I use? I've heard of spirit, also is it my computer? I have a windows vista home premium. I'm worried about jail breaking it but I just don't wanna spend money anymore.. What shall I do?
EDIT: I have the 4.2.1 software and I got my iPad on like spetember 14
