Buying a used Lumia 900 for use as PDA.

[Zenoctilles]

I personally do not have a cell phone, only an iPod Touch. However, I am interested in possibly getting a Lumia 900 used off eBay for purposes of using it as a WiFi-only PDA device. Plus, the Lumia 900 has one thing my iPod Touch doesn't have: GPS and turn by turn directions with offline maps. That, and a better camera.

One question, though:

Are all software and firmware upgrades handled by Microsoft/Nokia?

They are and arent handled by Microsoft/Nokia in a way. You can update using CAB Sender for all OS updates regardless of what AT&T does. To do it through Zune, AT&T would have to approve it first.

Doing some research, it seems that you update the OS via Zune, while you can update the firmware via something called "Nokia Care Suite" or "Navifirm Plus".

I just picked a Lumia 900 used off eBay for $200. I'll see what's on it and do some more research in terms of software updates from there.
