If somebody has a surplus single user license of Eagle Professional (>=5.0) Layout+Schematics(+Autorouter) and was willing to donate that to me, I'd be grateful for sure. :-)

What's the story with shielding? I'm nervous as it is with normal nokia phones, and don't like holding them to my ear for very long. Will there be any tests done to measure the effectiveness of any shielding put in place?

apparently it 'only' costs $5000 and takes 30 days to get fcc approval. something to consider at least.

needless to say, a quick bit of dividing means this is an extra cost of only €18 ($25) per device on a batch of 200 phones. money that nervous people like me would be very glad to hand over.

Full transmitter and receiver testing can cost around $5,000, transmitter only around $3,500, and the receiver about $1,500. If testing for other countries, such as Industry Canada or European CE, is desired, then the costs will go up, but will not generally double.
I'm not saying it shouldn't be done, but when calculating the costs one should use reasonable start conditions.

Thank you sincerely !
so it begun:
Introducing the Neo900 project - the first true successor for N900
we (the Neo900 team) are currently in the planning phase about a maemo5/fremantle-compatible successor of N900, with N900 look-alike (aka case) and a processor with more grunt and RAM.
This is already beyond the state of vaporware, see www.gta04.org which this will base on.
I.E. the GTA04 exists (350+ working units sold), what we're talking about are slight modification to GTA04 board to make it fit into a
Neo900, with housing, display, digitizer aka touchpanel, cameras etc sourced from the commercial N900 spare parts market. (though our primary target is to provide ready-to-run complete devices, we will also offer an option for you to buy the GTA04-NeoNinehundred board only, instead of the complete Neo900 device, to upgrade any N900 you already may have)
So it wll look like a N900, feel like a N900 and work like a N900, just way faster, thanks to the DM3730 CPU @1GHz and at least 512MB RAM (1GB depending on chip availability) plus maybe a few GB more of fast RAM-based "storage" as swap.
And - that's our plan - it will have all the functionality you're used to from N900 plus sturdy USB (that won't fall off the PCB) with full OTG support, all sorts of new nice sensors like gyro and altimeter and compass, and at your choice a GSM/UMTS (3.5G) or LTE (4G) modem that doesn't break (or when it ever would then you can fix it).
The AV/headset connector will offer new stereo line-in function on top of the usual mono mic and stereo-out and video.
We will add a general purpose expansion interface under that battery lid - funny enough it turns out it's a superset of what Jolla is using on their TOH interface.
Plus the whole device is 100% open, you get all the schematics and links to all the datasheets of the 'free' chips that are used. *), we don't work behind walls.
The project is about the hardware, we can't run a software development department to port maemo to the device. It's up to a community effort to establish this. Two volunteers already hollered: freemangordon whom you all know from CSSU, and FatPhil, an ex_Nokia kernel maintainer :-) Many thanks to both! And I mustn't miss to mention that a lot of other community members also offered to help wherever they can in our newly formed fremantle porting task force. Many thanks to all of you too.
Stay tuned for more to come :-) Please note Dos1's excellent post#5 below!
*)what we we possibly will hand out later on only are the Eagle project files to feed the fab with. We won't hand out the "shopping list" with all the commercial contacts. What's also not available are docs about the powervr graphics core, but device works without using that core. We don't have access to any modem firmware sourcecode or sources for other subsystem firmwares.
cheers

PS: I added a public poll, to allow for evaluating if we might reach the minimum of 200 preorders with a target of 700EUR per complete device (just ballpark figures!)

This more detailed info will be added to neo900.org in few hours and of course photos and videos from OHSW will also be added there

I am going to be buying a Gemalto PLS8-US bandplan modem, for the fact 700MHz LTE deployment is imminent in my area, I am to confirm with my contacts in the carriers about the validity and expected timeframe of this rollout sometime early next year.
The other item of interest in the -US bandplan modem is access to the 1900MHz band, which I am in negotiations with the regulator here in Australia, the ACMA, for non-common carrier broadcast access to the 1900MHz band as a "spectrum squatter" for use with the OpenLTE project - an open source LTE network end-to-end.
They have not said a flat out "No" yet, their engineering department will get back to me in the New Year. They have indicated co-ordination with the licence holder to the 1900MHz band (but not user of the band in my Local Government Area, hopefully) is needed, and that is up to me to negotiate that co-ordination, they will only name the licence holder, not assist me with those negotiations.
My interest in the Neo900 project is for the open access to the modem - certainly not of its firmware (although if it were leaked like the modem firmware for the GTA02 was, I would count that anonymous person as my personal salvation), but to the command subsystem, and interrogation of the modems status, with is abstracted away in Android, and totally not present in iPhone.
Yes, I like to watch NetMon quite a bit. I'm also quite a bit strange.
My eventual goal with all of the tech is the absolute lowest humanly possible latency bound end to end network for the real time control of mobile robots in a cellular sites footprint. This, as you would be aware, would have many, many applications, and I want this network to be about as self organising as possible - so imbued with a degree of AI.
Anyway, those are some thoughts, certainly, we stand on the cusp of a great moment with the Neo900 and OpenLTE projects...!
Long live open source!
Shane.
