From the Dropbox Blog:
Big announcement: the iPhone app is now available for 3.0! Go get it
Other stuff: We initially opted for 3.1 because API methods related to saving videos were not available on 3.0. This meant that videos taken within the app would be permanently lost in the event of a flaky/slow internet connection. This happened to us enough in testing that we felt it wasn ‘t a risk we wanted to expose to our users.
That said, Will, the maestro of our iPhone app, deftly crafted a solution for this problem. The result is what you see in the app store today! Will also says that there will be plenty of bug fixes to come in the future, as well as a huge feature push when 1.5 arrives.
Good stuff. If the lack of 3.0 support was preventing you from getting some Dropbox goodness on your iPhone, this update should be just the ticket for you. For those who are not familiar with Dropbox has been described by PC Magazine as the ‘simplest, most elegant file-sync tool ever ‘ “ and being a heavy user of it on the desktop, I heartily agree. The iPhone app gives you access to your Dropbox contents on your favorite device.
You can find the app HERE in the App Store, and it ‘s free.
