D'oh! Something happened at the OSHPark fab and the boards weren't cut out correctly. Only the milling was wrong (electrically they should be ok) and they were quick to re-submit the board to a new panel without my intervention (go OSHPark!). Being in Europe the shipping still adds quite a delay.
I could assemble the boards i got but as the new ones have already been sent i'll wait for them.
Here's a pic anway. I like the way the exposed PCB antenna looks :)
