Since receiving my replacement N8 at the weekend and being able to run Ovi Store 2.8 with update notifications, I've noticed that Nokia's IM Chat is awlays flagged with 'Update available' no matter how many times I install the update or by what means I do the installation (via Ovi Store or side-load).
The Ovi Store update says v1.0.1 (see image 1).
My installed version is v3.11.65 (see image 2).
Can anybody offer an explanation?
