Have you tried a hard reset, Hold the power button and home button at the same time for 20 seconds, or try it like this

1> Unless you are absolutely certain that there is plenty of charge left on the battery, connect the phone to a wall charger for at least 15 minutes. If it was just a low battery the phone will come on by itself. If it doesn't go to step 2.
2> Hold the HOME and POWER (aka SLEEP) at the same time. An Apple logo should appear in 10 - 20 seconds. Relase both buttons, wait about a minute, and your phone should be back to normal.
3> Occasionally it may be necessary to toggle the Mute switch a couple of times before Step 2. No one is sure why, but sometimes it helps if just holding the 2 buttons doesn't work.
