So that might be why all of a sudden my iTunes account today was "locked due to security reasons" and sent me to a apple page (from within iTunes) to re-activate it... I hadn't read this news, but it asked me to chose a new password for my account (couldn't even use the same i had before, since it gave me a "error" saying "that password cannot be used since it's the same password that was used last year"...).
Anyways, my iTunes account was working perfectly fine yesterday (last time i sync'ed my iPhone and updated 3 apps from the app store), but today i got this when i tried to update 2 more apps.
Another thing... i think (not 100% sure on this) that was here on MacRumors that i read that you could now authenticate up to 10 devices on the same iTunes account... is this correct?
I ask this because after i changed my password, it said "you have 4 out of 5 devices associated to this iTunes account" and if indeed the limit hasn't been raised to 10 it will pose a problem very soon for me... (Mac Pro, MacBook Pro, iPhone 4, Apple TV 2 and i'm waiting for a 2nd Apple TV 2 and a MacBook Air to arrive.... so that will make 6 devices, the Mac Pro is sharing my iTunes library from a 4Tb NAS drive).
Can anyone confirm me the correct number of devices you can associate to the same iTunes account plz?
Maybe the limit is indeed 10 and it's just me doing something wrong, or maybe i need to report this to Apple if my device count isn't correct...

It's usually not done on purpose. When signing up for Mobile Me, most people usually already have an iTunes account (and therefor an Apple ID) but Mobile Me automatically creates a new ID when you join. Most people don't even notice this when it happens.
I didn't realize it did this until the day I tried to change my main Apple ID's email address to my me.com address. It wouldn't let me. Why? That email address is already assigned to another Apple ID.
Got the same problem, and only noticed it today... I have my iTunes account since before Mobile Me existed, using my ISP provided mail address to create it... and i have the Mobile Me service since day 1 as well...
Now, it came to a point where i changed house, and since my current ISP does not operate where my new place is, i've been changing any and all subscriptions and services that are using my ISP's mail address to the Mobile Me address... tried to do the same with my iTunes account this morning, and got the same message you describe (even if i'm positive i did not create a 2nd iTunes account using my Mobile Me account).
