I need to start with a disclaimer. I own an iPhone. I do not plan on switching phones anytime soon. I don't care for AT&T and the slow Edge network, but the functionality and pure wonder of the iPhone is too much for me to even consider a new phone anytime soon. That being said, I love the new Sprint "Waitless" campaign.
Waitless is a digital campaign. An interactive campaign. I haven't seen any tv ads or print ads for it, but I have seen banner ads here and there. I can't even remember how I originally found the site waitless.org.

I think it was from Digg. What is waitless.org? It is a site that features 20 or so videos of time saving techniques for random common life tasks. Some of my favorites are Quick peel a potato, instant baby soothe, and instant sand removal.
These videos are short, only lasting a 15 seconds or so, but they are fun. I found myself watching every one. For a web "channel surfer" like me, that is pretty impressive. Other than the videos, there are some other fun parts of the site. You can use their time calculator where you enter in the name of something you do every day, like brushing your teeth, and then it calculates how many days/weeks/months you'll do that during your lifetime. As a bonus, they use that fun flashlight writing style that debuted with their "Speed" tv ad.

They also set up a sponsored YouTube dashboard that features user submitted videos for other time saving techniques, called SprintCuts. My favorite was the perfect circle guy.
Over time, if they stick with this, Sprint could amass one incredible collection of daily task time saving hacks.
This is digital done right. It is entertaining, interactive, quick, and social. It reinforces the brand. Before I had an iPhone, I had a Palm Treo and Sprint was my carrier. Sprint was faster and I miss that. Sprint = saves time. If I could use my iPhone on the Sprint network, I'd switch in a second.
