I wouldn't hold my breath for USA support.

Combo of

A). Network system and mobile economy rigged for subsidized devices
+
B.) The ground zero for software patents and patent litigation
+
C). American insistence to use non standard (/non-european) GSM frequencies

Equals pretty much dead zone for operation like Jolla.

Honestly, I don't see any point in them risking getting sued to high heaven & the hellish lows, with the only upside of selling small amount of devices to the most hardcore open source fanatics.


EDIT: My semi-uneducated guess would be that litigation case from just one major player (Apple, Google, Qualcom; etc.) would propably cost rougjly their current seed capital.
