Should I get an Acoustic Guitar or an IPhone 4?

My mum asked me if I want an acoustic guitar or an IPhone 4 for Christmas and I don't know which one I should get. I already have an iPod touch, a mobile phone and a computer. So what should I go with?
And if I got a guitar I would probably get into singing.

Iphone 4s volume buttons aren't working? - 1

Okay, so i just went to the apple store to get my phone fixed because the lock button wasn't working, so they gave me another iphone. I restored all my pictures and music and when i was testing it out to make sure everything is okay, the music volume is gone, it seems like it only works when i put my headphones on and thats when the music volume appears. Also when i'm in the home screen, when i press the volume buttons in the side, it won't work.plus i showed my dad and he said i was right. Is there anything i can do? I'm beginning to believe that these are just refurbished iphones --- The volume limit is off, just so you know.
