HTC F8181 (Smart2) for AT&T pictured
Also called HTC F8181, the Smart2 is (according to Engadget) coming to AT&T in the US. This may happen before the end of 2010, although nothing is confirmed for now.
In India, the Smart2 should cost about $215 (free of contract), so I assume its price for the US can’t be way higher than that.
The HTC F8181 Smart2 will have Wi-Fi, Office Suite and HTC Sense. Its display is probably QVGA (like the first Smart’s display). Other features are yet to be confirmed.
