SmartScreen provides widgets for your iPhone lock screen -- provided your jailbroken, that it. The demo above shows calendar, stocks, and weather, but the developer will be making an SDK available so other apps can get in on the widgety goodness. Conceivably Twitter updates, IMs, to-dos -- any information snippet really -- could be added.

On behalf of non-Jailbreakers, Gizmodo asks Apple to bake this type of functionality into the official fimrware, and let's face it -- they need something for iPhone 4.0 next year. Does it complicate Apple's current, zen-like lock screen? Sure, but that lock screen is currently so informationally sparse, maybe it could use some complication?

If you try out SmartScreen, let us know what you think.
