For some aparent reason Nokia or Microsoft pulled the S60 v5 version of the populair Live messenger from the Ovi store. The application seemed to work fine with good touchscreen support. Thanks to active users a mirror was created for those who did not originally download it from the Ovi store.
Installed on the N97 (mini) you have the option to use the Hotmail mail service in the messaging menu. You can also access the camera during your chat to send photo's and videos. The application can also be run in the background and will notify when a friend is chatting.
Notice: I have tested the application and it seems to run fine, the reason why it was pulled from the Ovi store is unknown. So use at own risk! Download Live Messenger for s60 v5 here
