i turn it off and then on again at night just cause its almost like a computer and you shouldn't keep that on all time too.
Exactly my thoughts. Specially when installing tons of apps.
I have had serious User Interface issues lately on my non-3G iPhone:
Example:
a) Incoming call: The phone starts vibrating
b) I slide to Accept call
c) Slider gets stuck at the end
d) Phone keeps vibrating
e) Backlight goes off after 2-3 seconds
f) I touch the screen to bring on the backlight
g) Now there is no slide to accept (or slider stuck screen). Instead there is an in-call screen with End Call.
h) I end the call, as such the call time outs and goes to voicemail anyhow.
i) Bang !! Now I see the home screen with this Green Current Call bar on top "Touch to return to call" with a call timer
j) When I try to click/touch "Touch to return to call" it does a loop of coming back to the home screen animation and the "Touch to return to call" comes back.
😕😱🙄😡 ....
😀 I'm fine with it considering the fact that its so much useful to me. I can live with a bug or two.
