ExpressCard and PC Card slots both seem in danger of going the way of the dodo right now, but they're not dead yet -- far from it -- which means that carriers still have a vested interest in making sure there are data cards ready to suck $60 out of your wallet in exchange for 5GB of 3G data. So far, AT&T's only been selling a USB modem that's capable of taking advantage of its newly-christened 7.2Mbps markets, which means they've got to get a move on with those other form factors -- and by all accounts, it seems that's where this AirCard 504 comes into play. Rumored previously as the "Triple Lindy," this bad boy should come bundled with a PC Card adapter (just like its AirCard 503 cousin) and feature support up to full 21Mbps HSPA+, although the best you'll likely ever get out of it connected to an AT&T cell is 7.2. We don't have intel on a release date right now, but we imagine they're itching to get this one out there -- the carrier doesn't offer any ExpressCard option at the moment, amazingly.

We can't say there are an awful lot of folks out there looking for a single mobile broadband card that'll play nice in both PC Card and ExpressCard slots, but for that niche that's intently paying attention, have a look at this. The Sierra Wireless AirCard 402 is the company's first to offer such 2-in-1 functionality, and it's designed to operate on EV-DO Rev. A networks handling speeds of up to 3.1Mbps (downlink) / 1.8Mbps (uplink). Users can also bank on the company's TRU-Locate GPS service to "quickly and accurately establish location for local searches and navigation." There's no mention of a price or release date, but it should be on hand for us to peer at during CTIA this week.

We'd heard it was coming, and now it's here -- AT&T's HSUPA network is now accessible to consumers who pony up for a Sierra AirCard 881 LaptopConnect card. The PC Card still supports HSDPA download speeds of 600 to 1400Kbps, but the upgrade to HSUPA means users can pump bits back up the tubes at 500 to 800Kbps as well. Customers will be able to score a free AirCard with a two-year data plan of $60 a month or higher until November 3 -- which is a shame for anyone outside New York, since HSUPA won't roll out to AT&T's other "select markets" until "later this fall."

Hot on the heels of the AirCard 595U, Sierra Wireless is expanding its HSUPA offerings with a new duo of USB modems. The AirCard 880U and 881U both connect to your Windows or OS X-based computer via USB, sport the company's TRU design features, and offer up a "theoretical maximum [upload] speed of 2Mbps," while downlink speeds tout a "theoretical maximum of 7.2Mbps." Additionally, in areas where HSUPA networks aren't available, both modems are "fully compatible with HSDPA, UMTS, EDGE, GPRS, and GSM network technologies on all frequencies currently used worldwide." The 880U is said to be "optimized for Europe and Asia, while the AirCard 881U is optimized for North America," and both units are slated to ship out next month.

BroadbandAccess customers, meet Sierra Wireless' AirCard 595U EV-DO Rev A USB modem, which is (almost) finally available to you through Verizon Wireless. Designed for use with your USB port, this EV-DO Rev A modem can also be connected through the included docking cradle, and even comes bundled with VZAccess Manager software. Additionally, the device boasts an internal, removable battery to "ensure there is always enough power support to handle peak or fringe area transmission requirements," and should be available for those interested on August 30th for $179.99 -- after you mail back a pesky rebate and sign your name to a two-year agreement, that is.

Although Sierra Wireless launched its AirCard 597E EV-DO Rev. A ExpressCard last summer, the device is finally making the leap to Sprint-Nextel's Mobile Broadband Network. Aside from the aesthetics, just a few alterations have been made under the hood, but we know you're most interested in how it allows Sprint customers to hop on the 3G highway with their ExpressCard-equipped lappie (or desktop). Of note, this rendition does manage to add assisted GPS (A-GPS) capabilities which "plots your current location on a map and then searches for nearby points of interest," a "high-performance (albeit beefy) integrated antenna to improve signal capture and data speed," and the new 65-nanometer MSM6800A chipset from QUALCOMM. Reportedly, Sprint will be demonstrating the card at this week's Interop expo in Las Vegas, and while pricing details were left out for the moment, the card should slip into retail channels next month.

At long last, the wait for Sierra Wireless' AirCard 875U on AT&T is over, as the USB WWAN modem has just popped up on the firm's Premier webstore. Unsurprisingly, this 2.2-ounce portal to the world connects via USB 2.0 and provides interoperable service between BroadbandConnect and EDGE networks. You'll find all the quad-band GSM and tri-band HSDPA love you could ever need here, and while Windows 2000, XP, and Vista users are all taken care of, it looks like the OS X crowd will have to sit this one out for awhile. So if you're interested in hopping on the 3.6Mbps mobile internet highway, head on over to AT&T Premier with $379.99 (or $149.99 with a new two-year contract) ready to hand over.

If the Canucks out there have been getting a bit jealous at all the Rev A love going around down south, your resentment ends now -- well, sometime this year, anyway. Thanks to Telus and Sierra Wireless, EV-DO Rev A connectvitiy is headed to Canada in the coming months, as interested users will be able to pop the AirCard 595 into their laptop's PCMCIA slot and reportedly reach peak speeds of up to 3.1Mbps downstream and 1.8Mbps upstream. Of course, it is noted that typical speeds will range between 300 to 400Kbps whilst uploading, and 450 to 800Kbps on the downward slope, but you Canadians will probably take what you can get, eh? Unfortunately, there's no set dates for the future rollouts, and "select markets" is all we have to go on for availability, but we do know that Telus will be charging $349.99 for the AirCard 595 sans a contract, or you can lock yourself in for a whopping three years if you've only got $99.99 to spare.

Verizon sure has tricks up its sleeves, especially when it comes to the Rev A network that it's been holding back from us. The Network is getting all its ducks in a row to have the UTS PC5750 release in February with the device priced at $269.99 full retail, $199.99 on a one year and $149.99 on a two year indentured contract. The device is a Type II PC Card (no luck if you need an ExpressCard) and UTS has increased the memory capacity of the device to 64MB Flash / 32MB RAM, making it the most well-endowed UTStarcom data card to date.

If you're still rocking a PCMCIA slot, and haven't filled it yet with some other tantalizing 3G option, Cingular just busted out its first UMTS/HSDPA laptop card, the Sierra Wireless Aircard 875, which might strike your fancy. Built by Sierra Wireless, who has been quite busy on this front of late, the card has theoretical peaks of 3.6Mbps down and 384Kbps up, and Cingular rates the actual speeds at around 400-700 and 100-120 respectively. While there's not much point to the purchase if you don't have Cingular's 3G Broadband Connect service in your area, the card can serve up EDGE data in a pinch. Without contract the 875 will run you $349.99, but with $149.99 off for a 2-year service agreement, and an additional $100 rebate when you sign up for unlimited data service, you might emerge from your local Cingular store relatively unscathed.

Word on the street has Helio launching its first data product as soon as tomorrow, which appears from this leaked kiosk mockup to be a Sierra Wireless AirCard 580. That would normally seem plausible enough -- assuming we can forget that the 580 is merely a Rev 0 device -- except for one critical detail: our sources tell us Helio's launch will combine EV-DO data with service through Boingo's network of WiFi hotspots. That leads us to believe that the 580 in the mockup is simply a placeholder for a different, hybrid card, or Helio's going to be assuming that its users are capable of bringing their own WiFi radio -- probably a safe assumption considering the percentage of notebooks that ship with integrated 802.11 these days. The partnership with Boingo makes a lot of sense, seeing how Helio's CEO is Boingo's founder and chairman, but given the ever-increasing ubiquity of EV-DO coverage (particularly anywhere Boingo would have a hotspot), we'll be curious to see Helio's marketing angle on this one.

Before we get you too excited, fair warning: there's not an ExpressCard to be found in the bunch. Instead, Sprint's decided to add another two PC Cards to the previously launched Novatel S720, giving them a grand total of three EV-DO Revision A-compliant data cards ahead of their network rollout -- it's just a shame all three devices fit in the same kind of slot. At any rate, we were always told not to look a gift horse in the mouth, so we're going to put a sock in it and thank Sprint for giving us options: first up is the value of the bunch, Pantech's PX-500, which'll clock in for a nice, round $0 on two-year contract. Next, the AirCard 595 from Sierra Wireless will match the S720's pricing, going out the door for $100 after signing on the dotted line. Expect both cards to drop before the end of the year, but until someone can show that the Pantech is demonstrably worse than its stablemates, we're really liking the sound of "free."
