Just as a friendly reminder, this forum does not allow the discussion of cracked apps or any software that is acquired by any means other than intended by the author, owner, publisher or distributor.
No problem! We fully support your right to jailbreak the device that you own, but we also respect the rights of software developers. If you don't want to pay for software, that's up to you, but if you want to talk about stealing software, that's up to us!
