Is it safe for you to enter a wifi network with a jailbreaked ipod touch? In other words, do the jailbreak software creators have any access whatsoever to my touch. Or could they steal info from my touch through my secured wifi network?
Your dad needs to read up on things, and throw the negative stereotype and connotations associated with the words "hack" "hackers" "hacks" "reversing Engineer". Not every single hacker on this planet wants to steal information, or inject malicious code/programs to your systems.
There are 3 types of hackers.
Ones who hack for bad.
Ones who hack because they want more from something.
Ones who hack to reverse engineer things. (exploiters)
The jailbreak and all programs associated with it from Quickpwn.com or iClarified.com or Winpwn.com or Devblog is 100% safe, nothing injected into your computer, no trojans, viruses, or keyloggers to steal any information you may think is valuable. The Dev team are hackers who reverse engineer Apple products (among others) and they hack because they have learned that the iPod touch/iPhone is more capable at doing more than what Apple lets on (exploiting).
As far as taking things through wifi from your computer, if a hacker is smart enough he wouldn't need to go through the iPod touch to get in. He'd just go right through the wireless router and its encryptions. But as ive stated, if he is a smart hacker he probably would rather hack a corporation rather than just one meaningless household. Example, would u rather steal from the guy in line behind you or steal from the cash register of the store you are in.
