Is a iPhone 4s 16gb good for me?

Should I buy and 16gb iPhone?
Music - 3gb ( 422 songs on iTunes )
Video - 3 gb ( Might add some movies )
Apps - 7 gb.

Should I get a 16gb one?

Yea that would be efficent, But if you plan on getting more apps than i would suggest on a 32gb. The phone onlu comes with around 13.2 gb of actual memory. The other 3 gb is already used up when you buy it.

Yes it can store ALOT. Even less GB will be good

Sure, if your concern is storage;however, I would deeply recommend switching to an android smartphone, specifically the galaxy s3 and the htc one x

I would recommend 32gb as With that there's always room if you want to download more movies or tv program's etc

Get what you can afford, but remember you can't add memory and it's better to have it and not use it, rather than need it and not have it. 3 gb for movies isn't very much. Maybe 2 movies. And not sure where you get 3gb 400 songs for music. I have 10gb on my ipad and that's about 2000 songs.anyway, go for the most you can get.

No! Get 32gb. I have lots of apps and stuff, but I'm always taking videos, and the videos take up gigabytes! It's crazy how big the files are.

Get the 32gb.
