If you tap the "contacts" menu on top, you will find options to sort contacts by online status and by telephone numbers. By default app displays all contact
I've had a good overall experience with the Windows Phone 7 beta, there's a couple minor hiccups, but it's a beta so they're forgivable. One thing I'd recommended fixing though is the way the contacts are listed, it'd be nice to be able to see who is online without having to view all their profiles individually one by one.
With out background what is the use off this app in smartphone ,every time we must open Skype and check who is in online,once we come to main menu we will be in off-line,
