Hi Sameer you're too clever! According to my Touch I am still at 1.9.9 (r30773, Jul 28 2011)
Hmmmm I thought the upgrade had gone through but apparently not. I'll try syncing again.
Ok it has synced and it says Update successful but I'm still at 1.9.9?
I have done the factory reset again and even though my Desktop is at 2.1.0 my Touch is still 1.9.9
I suppose I'll just have to wait...
