CTIA 2007: From Alltel’s Celltop to Nokia’s WidSets, mobile widgets are becoming increasingly popular, and becoming a preferred way to consume web services on handheld devices. ZenZui is the latest to jump onto the bandwagon. The startup is being officially spun out of Microsoft as a separate company and is coming out stealth mode this week.

ZenZui’s mobile widget technology was developed by Microsoft’s Research lab, patented by Microsoft and Microsoft also helped the group raise funding and acquire technology to become a separate startup. The company raised a Series-A financing round of $12 million from Oak Investment Partners and Hunt Ventures. We will catch up with their executives later today, and will bring you more details then. Meanwhile, you can see their YouTube demo of their interface here.
