Sony Ericsson has chosen Spb to create an XPERIA Panel version of their popular Spb Mobile Shell app.

Spb Mobile Shell improves the user interface of standard Windows Mobile apps displaying multiple information on one customizable screen such as missed calls, unread messages, weather, calendar, date and time, and contacts. The XPERIA Panel version is expected to make use of the XPERIA X1’s 3D acceleration as well as present new opportunities for the developer community.

Here’s the best news — expect it to be a free download when it is launched.
