Heyy guys. Ill get straight to it. I need a new phone. So I am going to the Optus (Australian mobile carrier) store soon, and am going to set up a $99 per month contract with Optus for 24 month, and will get the iPhone 3GS 32GB. Now my problem is, whilst on the contract, can I Jailbreak? I've heard stories that people who were on contracts, had to get their contracts pulled, and pay the remaining price of the iPhone, because they Jailbroke it. My question is not whether or not they will find out, but whether or not they will cancel the contract and make me pay the full price. Because I reeaaallly can not afford that. Thanks in advance.
