Hasta La Gadget!

Myriam Joire (tnkgrl) was born wearing combat boots and holding a keyboard; moments later she picked up a soldering iron. She’s been stomping, typing and hacking ever since. In her regular series, she’ll share her tips, tricks, and mods on everything from phones to netbooks — and be sure to catch her weekly on the Engadget Mobile podcast.

Things used to be simple: you either had a CDMA device with no SIM, or a GSM device with a SIM. If your GSM device was unlocked you could swap SIMs between carriers, and if was locked, you could swap SIMs between accounts on the same carrier. Basically, an unlocked phone meant mobile freedom. At first, the only complication was the different frequencies used for GSM in different parts of the world, which was remedied with quadband radios. Then 3G was introduced, with different frequencies used by different carriers in the same geographic area, like North America. Today, this proliferation of bands makes it difficult to build universal radios, and makes it less appealing to switch carriers. In fact, the only phone that currently supports all 3G frequencies used in North America is the upcoming pentaband Nokia N8.

The second obstacle was the introduction of special data plans, either requiring additional service layers (such as BlackBerry or Sidekick plans) or restricting the types of devices permitted as the iPhone and iPad plans do. What used to be as simple as changing APNs is now a Kafkaesque nightmare, complete with nasty “you are using the wrong data plan and we are going to send you a bill” text messages from carriers. Strike three was the micro SIM (also known as the 3FF SIM), popularized by Apple’s iPad and the iPhone 4. This smaller form-factor SIM is electrically compatible with the standard SIM we all know and love — and as such, it’s easy to convert a standard SIM into a micro SIM and vice-versa (but still, it’s one more hurdle standing in the way of happiness).

Let’s dive in and take a look at how it’s done.

Care about Samsung‘s GT-B3730? Probably not… but what if we told you that that very device is the planet’s first commercially available dual-mode LTE / 3G WWAN modem? Now that we’ve got your attention, you may be interested in knowing that overseas operator TeliaSonera — hailed as the first carrier on the planet to fire up an LTE network and make it available to Joe and Jane last year — is just about ready to start shipping the aforesaid Samsung. As of now, the only way to hop onto their LTE superhighway is with a 4G-only modem, and while it had promised a two-faced stick in the second quarter of 2010, we’re elated to finally put a face to a promise. The primary downside is that there’s no current way for the USB modem to switch from LTE to 3G (or vice-versa) on the fly; instead, you’ll need to kill the connection and start a new one when you leave / enter a 4G zone. Purportedly, the stick will play nice with both Windows and OS X, and it can hit real-world download rates as high as 80Mbps and upload rates of 16Mbps. Suddenly, a relocation to Sweden seems altogether more inviting, no?

Remember that cute-as-a-button 3G / 4G dual-mode WWAN stick that Clearwire outed a few days back? That little guy just made its way over to the Sprint side of things, giving folks yet another option when it comes time to pull the trigger on a device to get you onto the WiMAX superhighway. The Sierra Wireless-built 250U is available now through Business Direct and Business Solutions Partners followed by full channel availability by mid-July, with this bugger being the first in Sprint’s arsenal to offer native dual-mode support in OS X as well as twin antenna ports. Naturally, Windows machines are also compatible, and the minuscule design sure makes it more attractive than those prone-to-snapping alternatives. It’s available for precisely nothing so long as you sign a two-year data plan.

Lookin’ for yet another avenue to hop on the 4G superhighway? Fret not, as Clearwire has just doled out a trio of new products intended to help you do just that. Prior to today, you had only a smattering of options to actually tap into Clear’s WiMAX network, but the Clear Spot 4G (WiMAX only), Clear Spot 4G+ (dual-mode with 3G / 4G support) and Clear 4G+ Mobile USB stick have all arrived to give choosy moms more choices. The prior two are simply mobile broadband hotspots (think MiFi, but for 4G), with the 4G+ offering support for Sprint’s 3G network if you happen to leave one of those few WiMAX zones already lit. The USB stick is particularly interesting, as it’s the first dual-mode device hawked by Clear that’s fully compatible with Apple OS X. The Clear Spot 4G will be made by InfoMark and available to purchase for $99.99 next month; those who hate committing can also lease one for $4.99 per month. The Sierra Wireless-built Spot 4G+ (a rebadged Overdrive; shown left) demands a hefty premium for that 3G support, with an MSRP of $224.99 (or least for $5.99 per month) and a similar July ship date. The 4G+ Mobile USB stick (shown right) will support OS X 10.5.x and 10.6.x (along with Windows, of course), and can be snapped up today for $114.99 or leased monthly for $5.99. Head on past the break if you’re thirsty for more.

See that screen there? That’s from the minty fresh beta 4 of iPhone OS 4.0, which was just released to developers moments ago. Unless our eyes are badly mistaken, that’s an option to setup internet tethering on AT&T, something that WWAN warriors have been waiting for since… oh, forever. We’re downloading the new build as we speak, and we’ll let you know if we find anything out. Oh, and don’t get your hopes up too high — AT&T proclaimed that it was “still waiting on better network performance” before enabling iPhone tethering just three weeks ago.

Update: There’s a video of the screens after the break, just in case your belief was temporarily suspended for any reason. Thanks, Jerish!

Update 2: Well, this is interesting — we just updated an iPhone 3GS in Chicago, and we’re not seeing the tethering option. We’re guessing this is a glitch or just a mismatched carrier setting file, since so many others are seeing it, but we’ll do some digging and see what’s up.

Update 3: Okay, we’ve got it sorted — all it took was a quick network settings reset. Thanks, Gray!

[Thanks, Pete]
