Pretty simply, it's a small pocket notebook in the shape of a SIM card, both in unformatted (notebook) and formatted (address book) styles. Each SIMbook costs about $6. [Address Book, Notebook via Nerd Approved]

The inaugural book essentially mimics the video, but also happens to come complete with functioning QR code trickery and a SIM reader that you can use for fun (maybe profit?). The set costs $35 (purchasable here), but if you like, you can also print it out yourself. The downside is that you might not get the same, high quality look and you definitely won't get a SIM reader. But then again you save $35. [Citizen Engineer]

Not intended for swapping in and out of gadgets, this "embedded SIM" is fashioned from silicon (instead of plastic) so it can be stuck in pretty much any electronic device. Expected to arrive within the next six months, you should pretty much assume that from here on out, every machine you're using could be yapping on its cellphone. [BW via Engadget]

Why the hell would you need a motion-sensing SIM card you ask? Well first off, it could give any run-of-the-mill handset the capability to navigate menus, send calls or SMS messages with a simple shake or tap. It could even allow users to pre-program an emergency contact into the phone that could be called or sent a text message on a trigger of rapid movement—like a fall. So you are covered should you fall and break a hip or pass out in a bar.

The card was just introduced at the Mobile World Congress in Barcelona, so there is no word on when we might see something like this available commercially. But my guess it will come sooner rater than later. [PR Newswire via Uberphones]

Since there was no elusive SIM card slot found like there was on the HP Mini 1000, the modder had to solder in her own. So the hack is not for the faint of heart, but it's confirmed working. Check out the how-to and some photos of the action. [tnkgrl]

Sadly, watch phones still aren't cool, but Dick Tracy called the weekend news desk and approved the heck out of these his and her models from Chinavision. Sporting dual SIM cards, these black and pink pieces of geek arm candy do video and music, take pictures, and feature a touchscreen (complete with mini stylus). They just don't do cool. Unless, of course, you happen to look great in yellow and have penchant for battling wildly exaggerated baddies whose names reflect their physical appearances. Bluetooth headset included for about $148 (discount for buying in pairs—how cute).

Other features include: a 2.0 megapixel camera, 2.8" touch sensitive TFT-LCD display, 256MB/64MB ROM memory, MP3 and MPEG4 player, WCDMA modem, Bluetooth, and video call capabilities. Two models will be available the "Dragonfly" and "OMAP' with the latter having a faster CPU and tri-band network support instead of quad-band. Naturally, no pricing information has been released, which is just as well seeing as how this product is unlikely to make its way to the states anytime soon. Bummer. [TechFaith via TFOT]

I picked up a reader similar to this in Singapore recently, and it's functioned well enough to find itself a permanent place in my road warrior's bag. Not a bad deal for $19. – Charlie White
