I've uploaded version 1.3, it is waiting for review to get posted to the App Store.
Look for a brand new button on the top left of the Browse view - it is the 'Item Action' button and it pops up a list of things you can do. To start there will be up to two options - Email and Print
Email will let you send your sockCalc generated instructions to yourself or friends, straight from the app. Instructions will be attached to the email as an html file - you can save the file to your computer and do what you like with it.
Print will only be available with IOS 4.2 - if you don't update your device to that version the button won't appear. With 4.2 you will be able to print wirelessly directly to printers that support Airprint. See the Apple site for more details on supported printers.
