A bit of detective work by Engadget has turned up an FCC filing for the Acer S110. Comparing the FCC label diagram to the picture of the unannounced Acer Liquid Stream has led them to suggest that the two devices are one and the same.
The FCC documentation confirms the presence of 850/1900MHz HSPA connectivity suggesting that we could see the Acer Liquid Stream in North America.
There are still no details as to availability and pricing.
