Hi,

Recently I uninstalled/deleted an app called 'Whats App' as I wasn`t using it. Shortly after my handset restarted, a little notification type icon appeared, similar to a bbm, email notofication symbol.
It is a small pale blue square with half of a msn type person image in white to the left of it.
I can`t be sure if it is the 'Whats App' app that`s responsible for it being there, but it appeared immediately after my handset restarting.
Does anybody know what this is or can tell me how to remove it from the screen?

Any help would be much appreciated.
