My Iphone won't cut on at all?

My Iphone has been messing up the past two weeks. But now i'm starting to have serious problems with it. I wasn't going to ask any questions about it on here but now i'm. I desperately need answers now! Okay firs my iphone was having probles charging. That was just minor. Then we were having serious problems with it charging. I have to move it around ALOT to find a place for it to charge, it takes forever. Now i'm about to visit my dad for the holidays and hes super protective of me. ( over protective ) and my phone won't cut on at all! Hes the one that bought it for me and hes gonna wonder why its not on at all. The thing is my phone won't turn on at all, like I can't see whether its charging or not! And its just black. Its not my phone, my ipod has been doing the same thing. So has my other friends devices.I've tried switching adapters and cords. I have alot of chargers and a brand new one it doesn't work -___- My problem is what if my dad figures out how to charge it. Hes gonna be looking through my pictures and stuff I don't want him to be doing! Omg -___- i'm so unhappy right now & i'm leaving the day after christmas & my phone has been dead for 2 days. I need it to charge! The screen is black blank right now and its going to continue to be like that! Should I take out my sim card or what?! I have an iphone 4s. & my dad or anyone else is prob. Not willing to to take me to Apple. Omg please help i'm freaking out & i'm almost crying because, my dad will kill me if he goes through my pictures. Someone please help me figure out what's wrong with me phone! Please i'm begging. Thank you.

Try holding your lock button and home button down at the same time for like a minute or so. It restarts your phone, but it won't erase anything. I do it when my phone acts up!

  • Will a blackberry sim card work in an iPhone 4 if we cut the sim? My friend has a blackberry and wants to buy an iPhone 4 off someone he knows. I have a micro sim cutter that I used when I went from iPhone 3G to iPhone 4. If we cut down his sim it will fit in the iPhone, but will he still be able to use Internet and call people? Also, would his network provider be able to send him a new iPhone sim but with the same tariff? Cheers
