As soon as I realised phone was missing I had it blocked.
I had Dropbox already loaded onto the phone, the thief took photos on my phone and they automatically uploaded onto my computer.
Next was Android Device Manager which helped me track it to the exact address!
Gave Police address and photos of thief's lounge wall (yes, they had photographed their framed photos on their lounge wall!) - Police went tonight and identified said wall so they knew they had correct address.
RESULT!
Happy happy me :-)
I hope this post might help others to track their phone down in a similar situation.
