Jailbroken is when you can download other applications from others at hindi lng nklock sa itunes ang applications na pwede mong ilagay.i think when you buy something from apple it isnt jailbroken yet kasi yung ang original firmware nyan. There are easy tutorials on the net on how to jailbreak your iphone or ipod touch. if you plan on getting one go and get the one with the highest memory as possible so madami ka applications mailalagay. i just started enjoying my iphone and medyo bitin yung space kasi 8gb lang, pero i can watch movies, play music, go thru the net thru wifi, play rom's, ( playstation,snes,gameboy,etc. ) and im hoping for more nice applications to come out. if you need help PM me so i could try to respond to your questions. Good luck guys on buying your new gadget.
