You can now manage your AWS environment from an iPhone or an iPod Touch using Ylastic. We support most of the features of the regular web browser version except an S3 browser and SimpleDB Queries (We are working on these and will have them in a future version). Here are some screenshots of the iPhone version. BTW, clicking the ylastic icon at the top right of the screen on the iphone will refresh your data and take you back to the dashboard page from wherever you are in the app.

We are also working on a screencast and will have it out soon. Put that iPhone in your pocket to good use
