no. quite like some phone web surfing, or gaming before sleep, and also like being able to check emails during night easily as my work involves Aussie and Uk time zones so always active.
Can you just not use something else as an alarm clock and keep the phone downstairs, or set the phone to silent and put it face down?
In Cydia, the apps "Auto Silent" or "SBSchedule" will do this for you
Don't wanna jailbreak. And I'm on ios5 so don't even hav that option, do I?
I put my phone into airplane mode overnight. No chance of incoming texts or emails or calls waking me up but still have alarm clock and music to go to sleep with functionality.
