Iphone doesn't turn on any more!! need help!

i dont know about jailbreaking your iphone as a good idea but if you need just to turn it on press both power and home buttons for at least 15 secs... hope it will do...cheers!

Don't jailbreak it, and sure don't wait for God to fix it...
Do the previously explained re-set by holding down the two buttons for 15sec. If that doesn't help then restore it with iTunes. I know this sucks but you can back up from the last time before you tried to "break" it. IF not you will have to start from scratch with the restore, but that's better then a brick... isn't it? Good Luck!
