I bought PB 2-3 days back and it upgraded itself to OS 2.0.0.7971. All is fine. But when I goto Picture to change the wallpaper I do not see any option at all to change. I just see 2 buttons i.e 1 on left side which says: Back to Pictures and 2nd button on right is something related to HDMI etc.
But there's no option to set a picture as wallpaper.
I would suggest rebooting your Playbook. There are two ways to do this; the battery icon, or holding down (at the same time) power, volume + & - for 15 seconds. This should work
When I bought my Playbook, I installed 2.0 out of the box, and several days later there was another update that wiped out my factory wallpaper. Any idea how to get the full set of walls that it came with? Some of them are quite nice, even though I've got a lot of custom ones to replace them.
