They're lagging a bit behind the competition
in the dog-eat-dog world of high speed data cards, but one of Sony Ericsson's two models has a little trick up its sleeve that should still manage to win over a customer or three. The EC400 and EC400g both support the full HSPA suite -- HSDPA and HSUPA, that is, offering up to 7.2Mbps down and 2.0Mbps up -- on the 850, 1900, and 2100MHz bands, while GPRS and EDGE are supported on 850, 900, 1800, and 1900. Here's where it gets interesting, though: the EC400g adds an integrated GPS receiver, a feature occasionally seen on CDMA cards
but pretty unique in the GSM camp. Both should be available in mid 2008.
