Dropbox is a cloud based online storage solution that has been available for computers for a while. The service launched an iPhone app this week that allows the iPhone user to store content on the cloud.

To use the app you need a Dropbox account and the desktop software. Files placed in the Dropbox can be accessed from anywhere. That means anything you add form your iPhone while connected to the Internet.
Photos and video can be uploaded from the iPhone to the service and you can listen to music shared across the Dropbox folder. The only catch is that you have to pay for the service. 50GB of storage is $10 per month and 100GB is $20 per month. The app itself is free.







You can use 3GB of storage for free.
SugarSync has been doing this for a long time already…
