Here’s a rather interesting Apple-related discovery. ReadWriteWeb‘s Jon Mitchell was recently tipped off about a Facebook account supposedly maintained by an App Store reviewer. The thing is, as soon as Mitchell’s scoop was posted, the account was shuttered. Could this mean that it was legit?

The previously public Facebook account attracted the attention of a developer after he saw some unusual activity pertaining to his upcoming iOS app originating from the account. Apparently owned by a female Apple employee who goes by the code name “Dive Apple” and disguises herself as an upside-down cat, the account contained photos and videos shot with as yet unreleased apps. More often than not, these photos and videos showed some Apple hardware.

Probably the most noteworthy posting on Dive Apple’s four-year old profile was that of a series of photos showing what appeared to be her office desk at Apple. As you can see from the sample photo below, her desk is filled with Apple gear. But easily the most intriguing part of her desk is the sheet of paper marked as an “App Review Checklist.”

Is this also how your desk looks like?

Also worth noting are Dive Apple’s eight(!) friends. Like Dive Apple, most of her friends have “Dive” in their names and animals for their profile photos. They have varying levels of privacy, which, as noted by Mitchell, “makes sense for accounts designed for diving into apps and testing all the little Facebook-related bells and whistles.”

To be sure, Dive Apple’s Facebook profile gave away nothing in the way of confidential Apple-related information. If anything, it offered a sneak peek at the life — or desk, at the very least — of an Apple app tester. Now, I’m curious to know whether Dive Apple and her friends were responsible for any of the questionable apps we’ve been seeing in the App Store lately.
