Microsoft just launched SkyDrive for iPhone, the company's cloud storage and document collaboration service.

It will let you upload, store, and share things like videos, pictures, and documents.

SkyDrive is cool because when you sign up, Microsoft gives you 25 GB of free storage to use as you please.

Previously, SkyDrive had only been available through skydrive.live.com and through a built-in app on Windows Phone.

Grab SkyDrive for free here, and check out our walkthrough of the app below:
