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.

The cold war separating Sony Ericsson from North American 3G has been slowly melting as of late -- first with handsets, and now with modems. The MD300 isn't just Sony Ericsson's first 3G USB modem, it's also Sony Ericsson's first laptop modem of any sort to support UMTS and HSDPA on the 850 and 1900MHz bands. As USB modems go, it seems to be a pretty typical offering -- though it'll conveniently auto-install drivers on Windows machines, and it's not every day that you see a device like this offered in both "luxury black" and "metallic silver" shades. Who knew a modem could be a fashion accessory? Look for it in the first quarter of next year.

Like pretty much everything else in life, carriers' launch dates tend to slip, sometimes to the extreme (oh, come on, you can't tell us you've never procrastinated to the point where you couldn't make a due date!). To that end, we've gotten an updated look at AT&T's expected drop dates, and it seems like the wait has gotten a little longer for a few of the more anticipated handsets in the pipe. Some devices like the red version of the Nokia 6555 have slipped a couple weeks, while others -- the lowly Samsung A127 comes to mind -- have actually moved up. The Pantech Duo has also been pushed out from October 9 to the 30th, possibly to give the just-launched Tilt a little breathing room in the spotlight. Click on for the full list!

Update: A second source is telling us that the Duo is still tracking for shipment "on or about" the 9th. Of course, the proof is in the pudding -- but either way, at least we'll be getting our Duo on before the month's out.

Calling its E270 HSUPA modem "fantastic enjoyment" is strictly Huawei's own terminology here, but at two glorious megabits per second of upload speed (albeit theoretical) and up to 7.2Mbps on the downstream, well... "fantastic enjoyment," indeed. Granted, it'll be at least another year before we really start to to see widespread deployments of HSDPA's heir apparent -- which leaves the download speeds untouched from HSDPA while boosting the uploads significantly -- but we're glad to see manufacturers already have their eyes squarely on the prize for getting equipment prepped in the pipeline. Huawei says its E270 is also the world's first USB modem for HSUPA, surely bringing smiles to the faces of the expansion slot-challenged among us, and the tri-band 3G / quadband 2G radios should be enough to spread the love worldwide. No word on launch plans, but with the requisite networks necessary to take advantage of that juicy hardware far from in place, let's not put the proverbial cart before the proverbial horse.
