Hang tight, gang: The Apple tablet rumors are coming fast & furious with the dawn of a new week. The latest is a report that some tablet activity may be showing up in data from Flurry.

Analytics firm Flurry has reported to VentureBeat that they believe Apple is testing its new tablet computer at the campus in Cupertino -- make that 50 of them! Flurry’s data reveals that testing of the mystery devices “increased dramatically” in January after first detecting the devices as early as October.

Flurry is able to track such data by embedding their tracking code in apps that use its analytics service. Those apps then send information back to Flurry about the device that it’s running on, which is how the company first detected the unknown devices which are now assumed to be the fabled tablet.

“Apple appears to be going through its cycle of testing and polish, which is expected from any hardware or software company as it nears launch,” explains Peter Farago, vice president of marketing for Flurry.

Expected to finally make its first appearance this Wednesday, Jan. 27 at 10 am PST in San Francisco, the Apple tablets being tracked by Flurry appear to be running “200 different applications,” with games being the main apps in use by testers, followed by entertainment, news and books.

Most intriguing, the suspect hardware was apparently running iPhone OS 3.2, an as-yet unreleased version. The iPhone and iPod touch both currently run iPhone OS 3.1.2, a minor update that hasn’t been refreshed since its release last October. This runs counter to recent rumors suggesting that iPhone OS 4.0 may be released as a beta on Wednesday, and also provides further insight into whether or not the Apple tablet with run some variation of Mac OS X.
