Want a camera; get the 12mp protruding back with tripod mount. Back cover may also hold extra emmc.

It has it's drawbacks that backcovers won't be cheap, so getting more of them just to change colors won't be easy, but we have cases for that
Problem is that manufacturing wise that kind of modularity is pretty much as expensive as it can get. Something Jolla has no luxury of. Hell, just offering more than 2 colors seems to be too expensive for these big manufacturers.
Neither can anybody expect any 3rd party to make big investments to provide improved camera on a "other half".

Sure maybe (?) it could be engineering wise possible to actually put the phone in half, but it would be quite of risk to leave it with really crappy hardware and expect there to be better parts in the future.


That said, I would be all for cut the phone in half if it was possible as i'am quite concerned that the current "second half" to flop quite badly.

They said the specs of the other half will be open. 3D printable even. Perhaps they count on third parties to design and sell other halves. Which would in turn promote (the) Jolla for them, for free.

If the Jolla sells well enough in Asia, there will be numerous parties blasting out other halves.

[edit] AFAIK even Nokia discontinued their own cell modem branch, and I highly doubt Jolla has the manpower to develop and certify their own modem chip and FW, and they don't have the marketshare/volume to talk modem manufacturers into granting them access to cmt FW on a "do tweaks to it as you like" level.
Well, there's a SIM remote access thing that might or might not be supported by the modem Jolla used on their phone. If such thing is available, it could get exploited.

That's exactly the problem with this OH concept: you can't do everything via a "USB" 4 pin connector.

Samsung is coming with dual SIM, one for voice / GSM and whatever the operator supports, and WiMAX - when they provide coverage. You will soon find phones that run both CDMA for Verizon and GSM for AT&T in the US, but the Chinese has their own S-WCDMA that they support. It is just software now and two separate "ways" makes it easier to write the code, the radio interface definition is located on the SIM.

Drop it, and use this instead: Detachable bluetooth keyboard with 1800mAh battery.. Use A2DP profile, contains HID. If you need a keybord only, this comes at $15, th rest is for the battery.

IIRC, the Huawei USB aircards (Qualcomm 8200) can do GSM voice calls.

Two of those, and you get dual-SIM dual-standby.

I'd like to see a backcover for SailfishOS pull this off:
http://research.nokia.com/news/12133 - Nokia GEM Concept

wrap around screen, context aware, yea...

If they could pull that off, even as a limited tech exercise, that would be something kind of neat.

Yeah, or another complete phone, like in that case for iPhone.

Would it be possible to build a otherhalf with a stong magnet so it could connect to stuff?

other half us sooo overmarketed people already expect to much I am not even sure it has phycontacts just LOOK at the proto shown its only a bit of plastic but people her still thinks it has possibility for dualaim camera etc...

be realistic! Jolla is an upstart not comparable with samsun, nokia etc...

That's a great idea.
Don't need a strong magnet, something like the one on the Surface RT/PRO devices are good enough for mobile.

Just make 2 (waterproof) entry pins on the top corner, and on the opposite bottom corner of the backplate.

Something with a USB interface to pretty much handle all the Plug 'N Play features and charging capabilities of TheOtherHalf... that's the sweet point.

PS Don't spend time on the bs that is NFC and wireless charging, its a gimmick at best.
