Possibly this follow-up might make some folks feel a little better about the concern that was raised by Jonathan Zdziarski, author of the book iPhone Open Application Development and an iPhone Forensics manual:
“This suggests that the iPhone calls home once in a while to find out what applications it should turn off. At the moment, no apps have been blacklisted, but by all appearances, this has been added to disable applications that the user has already downloaded and paid for, if Apple so chooses to shut them down.
“I discovered this doing a forensic examination of an iPhone 3G. It appears to be tucked away in a configuration file deep inside CoreLocation.”
Engadget Mobile seems to think you all can breathe a big sigh of relief. According to John Gruber (Daring Fireball), via “an informed source at Apple” — the “clbl” stands for “Core Location Blacklist” and stipulates specific pieces of software that don’t have access to in the Core Location.
Possibly this is a better interpretation …. one never knows, does one? Check out John Gruber’s piece here at Daring Fireball.
