No, it’s not the Sidekick 4. And it’s not another Sidekick 3, but more like a Hiptop II with less hardware features and a Sidekick 3 OS. Sharp is still the manufacturer on this one, so it’s not the Motorola device we’re guessing is in the works. It sounds like this is going to be targeted at people who don’t want to drop the cash on the full feature set of a Sidekick 3. Rumor has it that it will be missing a camera (good for those in high security jobs), no miniSD card, and of course no MP3 player since there’s no storage. That’s about all we’ve heard so far. No word on whether it will be carried by TMobile, or what it will be named. We doubt it will be a Sidekick, or even a Sidekick Light, but you can bet the OS is probably similar since that’s what Danger banks on. We’ve heard that the hardware is similar, however with a different screen (lower resolution cause it’s cheaper). We’re still digging for details past that.

FCC Link

An anonymous reader tipped us off to these new exhibits posted on the FCC site. It’s the normal FCC submissions of confidentiality request and test results submitted by Sharp (the manufacturers of the Sidekick) but definitely a Danger powered device. They’re fairly recent, posted on 09/05/2006 with testing taking place in July-August.
A quick breeze through them and it looks like this may be some sort of updated Sidekick 3. The model number is given as PV200E (the original Sidekick 3 is listed as PV200). In addition, the sticker above matches the current sticker in shape. The only difference we’ve found so far is the GSM frequencies. Instead of 850/1800/1900, this one is 900/1800/1900. Our first guess was this is the (E)uropean version of the Sidekick 3. But that begs the question, “Why file with the FCC?” Perhaps this is an updated model with the intent to release in the US as well as globally, a.k.a. the Hiptop 3. Maybe this is one of those Limited Edition Sidekick 3s? I guess we’ll find out when the confidentiality request expires on October 12th. Drop your guesses in the comments

The manual pages look very familiar. Some interesting observations:
- The SonicBOOM manual page we received matches up almost exactly with the “Music Player” page, so looks like a name change.
- No video support
- There’s a considerable section on the “Danger Service Privacy Notice” and what sort of information they collect and share.
- Yes, USB 1.1, not 2.0
- MP3s play off the miniSD card
- EDGE support!
- Bluetooth (as if noone saw that coming)

and I’m sure our commenters will have some other things to point out…

The FCC has updated the page and it looks like we’ll get a chance to see some official documentation, photos, and more very soon. Right now it’s returning a server error, but hopefully that will get straightened out soon.

It’s official, at least as far as the FCC is concerned. The filings for the Sidekick III showed up on the FCC’s website. We’re not sure why they didn’t document the feline behavior modification chip, but we’re sure that’s still being kept under wraps. It’s going to blow the market open for pet control like no other device we’ve seen. The previous pics were legit (to some extent) and we now have the newest pics for your viewing pleasure. Some of the rumours that are confirmed: Bluetooth (for all you lexus drivers), miniSD for expandable memory, and a 1.3 megapixel camera. Many are assuming the miniSD is meant for expansion for multimedia playback, meaning video and MP3. This hasn’t been confirmed yet, so stay tuned for the exact details. At this point we can only guess at some of the software features based on the capabilities of the hardware. Still no release date though, but we assume it can’t be far off if this information is now public.
