It's true that e.g. Skype or Shazam are not available for Nokia Asha or other Series 40 phones at the moment. Apart from those 2 apps is there any other specific type of app you are looking for?
For example this article gives a examples of apps for Asha 311: http://conversations.nokia.com/2012/10/10/my-essen
...not to forget also the EA games bundle: http://conversations.nokia.com/2012/10/03/ea-games
Btw. regarding VoIP calls - it's seems that Asha 311 should support Nokia VoIP natively (http://www.nokia.com/global/products/phone/asha311
but I can try check/verify how that works in practice.
Here's is what is said in the device userguide (http://download.fds-ncom.nokia.com/supportFiles/ph
