Yes you can. Redsn0w.
Mine is jailbroken, mainly for winterboard and some of the really useful tools like infinitifolders.
I did before I accidentally upgraded :| Bring on the new iPhone.
NEver upgrade to ios7 WORST THING EVER
I've always been too scared to jailbreak my iPad. If something went wrong, I'd have nothing left to access the Internet with.
dizzy mention free apps and shit but on top of that it just makes your phone more convenient. like dont you hate how your browsing clraik on your phone and you get a text so you have to go to the msg app text back and then go back to what ever browser you were using to look at clraik,
if you jailbreak and install a tweak called bitesms, you can literally text and reply everywhere with a push of your volume button!
