Expose.
MobileExpose is soon to be released on Cydia (the underworld app store for shady jailbreaking types) and although currently unavailable it will apparently be available for download soon.
Dashboard widgets.
Unfortunately just a concept, but completely plausible. The UI elements suggested here look utterly sound to me, I want it.
¹I personally think Apple should sell (desktop) dashboard widgets on iTunes. It would increase the quality of the software and drive interest in development.
²The voiceover dude sound exactly like SVEN, the Swedish design team from How I Met Your Mother (S04E08).
I'll leave you with one last tasty morsel of probably-never-gonna-happen-dreaming. It's not a video but I think you'll approve.
A home screen that dosen't suck.
Created by the design geniuses Teehan+Lax, this idea displays things important to you such as weather, stocks and email. Not just a frigging clock. Click here to see what the rest of the above mockup would look like if you were to continue scrolling. After they received aproximately a baziggajillion comments / requests / firstborn children to make this possible, the dynamic design duo have now announced they are toiling hard to make this a reality. One would imagine this means it will be a jailbreak app when ready.
¹the top weather part reminds me a lil of the uber sexy HTC Sense UI skin for Android phones. If only they included that retro-cool flip clock also.
²You may be familiar with Teeh+Lax's amazing (and free) iPhone UI elements PSD, a great resource if you'd like to mockup your own app / webapp / mobile porn site mockup.
