What does it mean to jailbreak an iphone? - 1

I'm going to be getting an iphone soon && my friend says i would need to get it jailbroken what does that mean?

It allows you to download additional applications, extensions, and themes that are unavailable through the official Apple App Store.

First of all, jailbreaking will void your warranty, but in most cases if you are having trouble with your iPhone just restore it with iTunes before taking it into an apple store to get it repaired and they can't tell. Anyways jailbreaking is a way that you can put apps, tweaks and themes that aren't approved by apple on your iPhone. In my experience these tweaks have greatly improved my experience. There's next to no risk of damaging your iPhone as long as you follow the instructions given by the jailbreaking program. I suggest googling "redsn0w".

When you jailbreak and iphone. You can install extra features that you wouldn't be able to do on an unjailbroken iphone

For example: if your iphone is jailbroken you can… Have more apps, change the names of things, have moving wallpapers, install android features to make you phone look like an android phone. Etc.
