It looks like Kevin Tofel may have stumbled upon some good news for Nokia S60 fans after seeing a strange image in his Google ads. It seems that there is a viral campaign for the Nokia N81 that leads us to believe we will see an August 29th launch date for this Nokia N91 successor. I actually still use the Nokia N91 to listen to my Yahoo! Music subscription while working in the yard and getting fit. A couple months ago Engadget posted some photos originally found (and then removed) from the Symbian Guru site that detail the N81 slider smartphone.
The rumored specs of the Nokia N81 include an 8GB flash memory, Bluetooth 2.0 with A2DP, quad-band GSM with 2100MHz HSDPA (hopefully this will work with AT&T's US 3G network), WiFi, 3.5 mm headphone jack, 2.4 inch QVGA display and 2 megapixel camera. I like the slider look to this device and am looking forward to an improvement over the N91.
