I disagree. I’m a perfect example. I had no idea what jailbreaking/rooting were and saw no point/purpose in doing so at first until I had it explained to me.
Flashing your car’s computer is much different that clicking a few buttons on your phone/PC.
Another point...you can go into the classifieds and find people who will do the root/jailbreaking for you for a fee.
The market for it is out there and as I’ve been saying all along, it’s a matter of either stupidity, laziness, or both.
The rooting/jailbreaking process is down to the point where it’s nothing more than downloading a program, plugging in your phone, and clicking a button. People are going to PAY someone to do that? REALLY? They’re that dumb or that lazy? You have perform more steps then that to setup what you want synced in iTunes.
Not really that hard. On most cars it's as simple as replacing a small board in a slot on your ECU. It's still not a basic user function. It's for the more advanced or more daring.
The biggest holdup is who do you go to for help when it fails? Hope the online forums will help? What do you do if you bricked it? Your carrier certainly won't help you, neither will the manufacturer. If you keep it stock, you can get the phone re-flashed at the carrier, or just get a free replacement. No matter how well the process has been packaged and simplified by those (admittedly very talented) modders, it's still hacking, and it comes with risks.
