Does anybody know of an iPhone application or shortcut that allows you to save your email address access it via a shortcut? This would be super useful when filling in forms in Safari or in when your email address is required in an application.
An excellent application for shortcuts is Smile Software's TextExpander touch. Because of limitations in iOS, it doesn't work to expand shortcuts in every app (including, sadly, all of Apple's apps). From the manufacturer's site:
Given the current feature set of the iPhone OS, TextExpander touch cannot work in the background (as it does in Mac OS X), expanding text snippets while you work in other apps, except for apps with TextExpander-integration built-in. You must first compose your text in the TextExpander touch Compose screen, and then transfer it to another app.
