I got the external antenna. I've done a quick test by using WinSCP to upload a large file. I got ~1.5 MB/s on an A+ with hat, 2-2.4MB/s on a 2B with hat, ~2MB/s on a Pi3 with hat (it disabled the internal wifi and both BT), and 2.5-3.5MB/s using the Pi3 onboard wifi. All tests used the same SDCard and onboard antennas (they were less than 6 feet away from the router).

It's now called pHAT :) (I'll edit the subject line of this thread to reflect the change). Good call guys! :D

The pHAT is nice. The issue is that not every one is able to solder the 40 Pin Connector. The HubPiWi Blue is better alternative as it has 3 USB ports along with a WiFi and a Bluetooth. It does not require soldering the 40 Pin Connector. It makes connection through the Pogo Pins.

I just picked one of these up and first thoughts:

First, it doesn't include a pass-through GPIO, so unless you get something like a pi-borg-2, you'll cut off your GPIO connectability for stacking hats.

Out of the box, wifi worked without a fuss. No such luck with the bluetooth. I went to their website and it said something about resetting the uart clock speed in the boot/config.txt so I did that - still no luck.
I checked that I had bluetooth support within the configured software, I did. Tried a few other basic things. Still no luck.
Posted to their support forum, four days passed with no responses.

As far as bluetooth+wifi usb dongles, I picked some up a cirago the $17 range that were recommended by another user on forums. They've worked fine on all my other pis.
