If you often find yourself entering your email address into text messages and submission forms, new jailbreak tweak Double At would probably be useful to you. The tiny add-on automatically enters your email address whenever you double tap the “at” symbol.

“The package will allow you to automatically insert your email address into a text field upon double tapping the “@” key,” writes Cody at iDownloadBlog in a Sunday article. “While you could accomplish this with an app like Xpandr, Double At is much more simple. This utility is for power users who are constantly sending out their email address from their iDevice.”

Published by iSam, Double At is available as a free download from the Cydia jailbreak application store.

“I guess it doesn’t have to be your email address. Double At allows you to program the text from the Settings application, so you can pretty much put anything you want. Once it’s set, you can insert it into any text field by — as the title suggests — double-tapping the “@” key,” the article continues. “If you already have Xpandr, obviously you won’t need to pick this one up. But if you’ve been looking for a condensed alternative, check out Double At.”
