The names seem to be the only things that were revealed by the leaked image, so the rest of the specifications are left up to your imagination. Some folks claim that the HTC Era 42 could very well succeed the old-school T-Mobile G1, considering how the T-Mobile G1 once carried the “Era G1” codename. When you throw in the number 42 into the mix, it might just pave the way for a HSPA+ device that has been rated for 42Mbps speeds on the downlink.
As for the BlackBerry Armstrong, this will not be a BlackBerry 10-powered device, since those will arrive only sometime in 2013. Hence, this will be an entry level smartphone, with the BlackBerry Curve 9320 being the most probably candidate.
