If you are using Smugmug to store and share your digital images and video clips, do yourself a favor and pick up Blossom SmugMug Mobile ($2.99) by Kupuk. With Blossom you can browse your SmugMug albums blazingly fast on your iPhone.
Blossom makes easy work of sharing your SmugMug photos on Facebook and Twitter as well as saving the image to your iPhone's photo roll.
The latest release added functionality to play your smugmug video clips on the iPhone as well.
The quality of the images and videos is excellent, viewing videos via 3G is possible and is quite quick.
Blossom is now my go to application for showing off my SmugMug galleries, 3 dollars well spent!
