OK. I have a Lumia 720. Recently, I reset my phone and when I had everything set up again, I found the where it says Extras+Info, I have Lumia Denim. On that page, I have things like: Firmware Update Notified 1.1.0.5; Glance PinBoards App Agent 1.3.1.7; Lumia First Use Experience 1.10.0.4; Lumia Share 2.5.1.0; Rate Us 2.6.0.3; Silent Installer 1.6.0.6; SIM Unlock 1.0.0.5; SMS vCard Receiver 1.2.1.7; SpamFilter 1.9.3.1.
This is followed by a number of entries like Manufacturer's name (RM-885_eu_auro1_271); Mobile Operator (I won't list this). Configuration ID (445284), Core Build ID (3058.50000.1425.10479), Application Version (3.12.0.3), Build Creation Date (02/07/2014).
The OS Version is: 8.10.14157.200
The Firmware Revision Number is the same as the Core Build ID that I mentioned above.
So, is this Denim or what?
Edit: And yes, I do get the Weather app info on my Glance Screen, which is pretty cool!!!
