My wife's 950 turned up the day before yesterday and she's very happy with it. There was a major problem with it losing WiFi though.
It'd connect to our home wifi, then after a short while disappear. It would then spend all it's time searching, but reporting no networks. The only way to get connection back was to reboot the phone. But then it would re-occur.
I then noticed nothing from the Store would install. I'd get constant errors. The phone was also getting really, really hot.
I tried multiple resets to no avail; soft and hard.
After searching a few forums I tried deleting the 5GHz connection and connecting to the 2GHz one. It remained stable and apps started to download. Then a phone update appeared out of the blue, despite previously reporting that none were available.
As far as I am aware it's been alright today, but I haven't tried re-connecting to the 5GHz.
It came with a free dock, but I can't see us using it. So am considering selling it to off-set the price of the handset.
