1) Can I quickly turn my phone into a hotspot. I can disable wifi, change the brightness, etc. but I don't see a way to turn my phone into a hotspot. This remains buried in settings and is annoying to take my phone out and go through the process everytime I want to use my laptop on a bus. 2) Any way for tracks that are being played in the music app to be scrobbled to last.fm? I've only been asking for this since the 3G.
