To all gong cheebyes who dunno what is Jailbreak, pls do your own research before you jailbreak.
Jailbreak is fairly safe based on my own experience. If anything goes wrong or if you want to send your iPad 2 for repair, just reset to factory settings and your jailbreak will disappear.
Also, remember to backup all your data before you attempt to jailbreak. Usually if you just sync with your PC or laptop, it will be backed up.
Jailbreak your iPad 2
Dsiclaimer: Try this at your own risk. I myself have jailbroken and have not experienced any screw ups.
1) To jailbreak your iPad 2, simply open Safari browser on your iPad 2 and open this url
http://www.jailbreakme.com and tap the 'Free' Button and then the 'Free' icon will turn into 'Install' icon. Tap it.
Reboot your device and Voila! Your' done. That's it. You don;t even need to connect your iPad 2 to your PC or MAC to get this jailbreak. All you need is your iPad 2 and connection to internet.

Now that your iPad 2 is jailbroken at this point, it is time to download Installous which is kinda like an Appstore to download paid apps for free.
