Contact warranty support and tell them something is wrong with the board. I will bet they will replace it with the WWAN enabled board in due time.
Upgrades: 2GB RAM, Intel Wifi 5300 N Card, 3rd WLAN Antenna
Coming Soon: Internal 8GB Flash Drive (Dual Boot), Internal USB GPS, Internal USB Hub

I tried it.
Bought the PCIe mini card connector obtained from Mouser.com

Bought a 5520 3g card on Ebay from a chap in the UK (I won't post a link although it's easy to find)
Got the SIM socket from Farnell (never got to even solder this on)

Soldered on connector, added some plastic insulation under the card to stop it from shorting the motherboard vias, plugged in the card and turned on.
After a few seconds the mini turned itself off. Oh dear I thought. Strong smell of burning. Bugger!
Removed the card. Two vapourised pins on it. Part of the socket melted.
Checked all soldering for the umpteenth time with jewelers loupe - no bridges. Removed socket, cleaned up board with isopropyl, soldered on another. Same result. Gave up!!
Mini still works so that's a bonus!
