The iPhone unlock is going on sale today… for a cool hundred bucks. If that’s not enough to make you think twice, then read the disclaimer which says that if Apple happens to re-lock your iPhone via a software upgrade or something, they will charge you again to re-unlock it.

A hundred bucks and no guarantee that you won’t have to shell out another unspecified sum more times in the future? The one-time high price one could get past, but after that, you’re kind of at the mercy of the winds of fate to pay open-ended amounts of money to keep what you might think is already yours.

I kind of expected this to go for fifty bucks with a promise to do their best to re-unlock for free if Apple re-locked it. But then again, we’re talking about getting away from a 2-year commitment to AT&T. When you think about it, why should AT&T be able to lock you in for that long when they aren’t even subsidizing the phone’s cost? If you can get into a cheaper plan without the long-term commitment and possibly better service, then the $100-plus-who-knows-what might be a deal… especially if AT&T doesn’t even serve your area.
