This is actually something I thought about last night. There's a television in my bedroom, and depending on how tired I am, I'll also have my laptop and a cell phone. Although I use my phone primarily for an alarm clock, I do find times where I wake up and can't fall back asleep, so I pick up my phone and play with a few apps. It's strange because my body feels like it should be asleep, but I force it to stay awake to read a blog post or a few more tweets. Obviously not good. I do like the idea of a "limitation app" that would prevent things like certain phone numbers calling or limiting emails till the morning, but without a jailbreak I'm guessing that's fairly impossible. If not, though, that's something I'd buy in a heartbeat.
