Something that looks like this(I did not draw that :-)

Finished device would be the size of Palm V.

Edit: added info and links.

just wondering if you or anyone els has exsplored the idea of using 3D plastic printing to buld a modified case for your needs?

I'm with you there; for various non-technical reasons (read: the wife won't switch), I'm stuck on T-Mobile. Not that I'm complaining about T-Mobile service, but "upgrading" to a phone that won't work with my service plan is a no go. I would also like to see this thing packed with as much RAM as possible, and Bluetooth low power. Those are my two biggest pain points right now on N900. Everything else is just icing, albeit very welcome icing

Of course, if I'm really dreaming, I'd like to see a truly flexible software defined radio (or multiple ones!) put in, so that any future wireless standards could be easily handled by loading different firmware profiles/software configurations. Just think: no more missing out on newer standards like NFC, or backwards compatibility with devices such as ANT. A higher megapixel camera would also be nice, but it's not a dealbreaker. Faster CPU is good, as long as it can be scaled way down on the power consumption (another pain point).

Please refer to http://m2m.gemalto.com/products/m2m-advanced.html (recommended: PLS8-US, PLS8-E, PXS8) and pick your favourite. We build to order :-)

For the rest of your requests: we're doing our best. Please refer to all this got discussed in this very thread before.

Thank you, not just for this, but for all you do! As a code monkey, I'm not much into the hardware side these days, so I highly appreciate all this work; it's what I've been looking for for a while.

Sorry about the duplicate requests; I hadn't had a chance to peruse the whole thread yet.

Also, I'm not sure how much help is needed (or how much time I could spare), but I used to hack on RTLinux and would love an opportunity to help with software, even if it's just code reviews. One of these days, I ought to find a way to get paid full-time to do Linux kernel hacking again . . .

EDIT: 129 pages, is a *lot* to peruse, but I suppose this comment isn't helping; perhaps a wiki page to boil it down/keep most recent developments on, and put a link to that at the top of the first page. Also, I did find the links to the SW dev side; I will keep an eye on those; count me in!

Thanks to massive help from Xes, I've been able to sort out the camdoor proximity sensor component and partially the magnet sensor backcover detector.
Still pending and a HUGE problem: the SMIA95-16pin THRUboard connector for the main camera module. Any help much appreciated!

cheers

PS: @npsimons: Help on the FPTF much needed and highly appreciated. Please /join #maemo-ssu on freenode.net and talk to the guys there.

Sorry./j

If it it possible to separate those two parts, than I can set the keyboard part a little higher than the upper-PCB, so that the screen and keyboard will be on the same level. Other wise the screen will be a few mm higher off the pcb than the keyboard, even after removing the sliding mechanism.

If you want to lift the kbd a few mm to make it flush and plane with display, you easily can attach a second kbd to replace the original one.

Are you saying that it is possible to use other batteries than the N900 battery?
Edit: is it possible to use Note 2 battery?

Of course it's possible to use any standard chemistry 3.7V LiIon cell with Neo900 - if you find a way to connect it instead of or in parallel to the BL-5J. Where you place that battery is another problem. I think there are companies that build LiIon to order, in low quantity. No idea abut Note2 battery.

Hmm.. It looks like neo900 will be coming out before Jolla.

Not necessarily. Jolla's on 27th November for Finland (still limited). For others probably December or January. At OHSW the Neo900 isn't complete either, just to showcase the modem and others (I'm not sure what others are :P)

I did. But milling it out of aluminum (or titanium) is better because the case will be much stronger. 3d printed plastic case needs designed in reinforcements and such, and the surface has not as nice finishing as milled alu.
Nokia has released cad drawings for some lumia cases which were 3d printed by users, and they broke very easily.

And Estel has build a milling machine, would be waste to 3d print
