there is always a solution, first of all, update to the new os with a jailbroken firmware(when it will come, if ever)can be a solution, keeping exploits safe is another, also i think iOS it's not the safest os ever created. the more you challenge the hackers to find something the more they will. There was always a bug "ready for use" so maybe noone looked very deep.
If there wil be the need hackers will find.
