Clean-ish desktop on my S3. Had it a while now, but haven't cracked it yet. I'll wait for Jelly Bean upgrade, then see about cracking it - primarily to get rid of all the bloatware.
800 / 900 is prettier, mainly due to unibody design :Р
Just one thing I don't understand - why Nokia would make phones that differ by $150 in cost, look completely same, except for 20% size difference? :S
Its good to have the option to choose sizes of the same design, like rims or lcd screen etc. I really hoped the new wp8 Nokia would look the same as the unibody n9/lumia 8/900 ones. Too bad the 820 looks different, but im sure i can get used to the 4.5" screen on the 920
No one knows. Nexus 7 already got an alpha CM 10.1 build, so it shouldn't take too long for other Tegra 3 based devices.
The latest 4.1.2 based nightly builds have been really nice though, very stable and battery life is much better than before. Once the 4.2 alphas do come, they will propably be a bit buggy for a couple months.
