your iphone ties you to a unique AT&T account. it's the holy grail since trying to figure out who is who has been a problem in the last 10 years with internet advertising.
you open an app and it sends known data about you which is then compared with other data that has been collected to market to you
Um... No Not right at all.
Developers have no access to who owns what phone based on the Device ID.. Apple is the only one who has that information... AT&T Identifies you by your SIM card. Something they have been able to do for Many, Many, Years and way before the iPhone was even a glimmer in Ole Stevy boys eyes.
So yes you can identify a specific device but you can't identify an individual unless they enter their information into your app and if they are doing that you better have a EULA and Privacy Policy built into the App having them agree to how the info will be used.
I'm working on an App that will do exactly what is described in this lawsuit.. Use the device ID plus user input for more targeted advertising. But I sure as hell am going to ASK my users if they want to participate before that information is used and it will have an Opt-Out feature if they change their minds.
I really don't understand what all of the hoopla is about though as A LOT OF OTHER COMPANIES have done much worse for years and years...
I work in the advertising business and trust me, companies like Valassis have much more information on you than you even know, and guess who gave it to them? The US Postal Service and the Census..
Hah if you use Google, they know where you are at all times, watch all of your searches, know your calendar info, read your email, Know what TV shows you watch (even the ones on skinimax) and will soon know what color underwear you had on last monday..
Don't pretend to be shocked at all of this and don't go trying to sue over it. Most of it is 100% legal. The only ones I see running into issues are the developers who conveniently forgot to tell the user that they were collecting the info or provide any type of privacy policy.
Sucks to be them..
