2. What's your favorite beer?
I studied device electronics and microtechnology during my study I was working at Siemens preparing electronic boards with thermo couples to optimize reflow and hotflow soldering processes and desoldering and resoldering flip chips with special machines. During that time Siemens produced mobile phones and was looking for a lead free solder paste and halogen free PCB.

In the past I was soldering magic chips into PS 1 and 2, I also exchanged flexcable for my A780 for example. I am brave and keen to open everything and have also good skills to use a soldering iron.

I own 3 N900 2 in very good condition and one I can use for training. I only open a phone from somebody else, if I successful exchanged a board for myself.

I drink nearly every beer except "Sternburger".
I don't know if I am suitable for this, you will only know it afterwards. I have a public liability insurance, in case I drop your phone.

Watch out, prolly you're not legally liable for damages occuring during you helping somebody with technical stuff when the one suffering from such damage asked for the help. So your insurance won't cover that either.
Case would be different when you snatched away (or borrowed) the device from owner and then applied some rework to it without owner knowing about and agreeing into it.

Just a heads up

[edit] I think you're more than just "suitable for this" :-) And thanks for the kind offer to help other customers.

answering a mail with questions Neo900 UG received. I think everybody should benefit from answering them.

no (or not more than anything in Neo900 is)

because we need electrical/logical as well as mechanical/formfactor compatibility

We will use new spare parts, not parts scavenged from old N97

The camera is connected to system via the B2B connector the N97 camera comes with, which is one of the reasons we prefer it over the SMIA95 socket of N900 cam module. You're free to attach any camera module that can provide the same signals.

short answer: yes, exactly.

The flashlight will use new LEDs (we wouldn't even know what's the original LED component) and thus might be stronger, However we can't change anything about focusing which is done by N900 case's integrated fresnel lens

see above comments. One more: Neo900 is about enabling user to re-use software made for N900, this includes canera drivers etc.

AIUI you refer to the "USB port falling out" issue? We tackle that by using through-hole type of a micro-AB socket which is supposed to be way stronger than the one in N900.
For alternative charging please see our HackerBus whitepaper - in short: there's an option to attach chargers, under battery lid. Well suited for stuff like inductive charging (or PV-cell) or gold pads on surface of battery lid that a cradle's pogopins could attach to.

We hardly could, even when we would plan for it. We need same form factor once again.

We don't recommend nor support OC. Even while it's possible on Neo900's DM3730 CPU as well afaik, OC is considered dangerous and destructive for the SoC and will significantly reduce life span. Note that any warranty will be void when overclocking the device.

Yes, please see post a few above, we verified 1024MB (1GB) RAM PoP chips to work with our SoC, and we're about to secure/source a sufficient number of chips.

The CPU is 100% compatible to the N900 one.

That's up to the OS, which Neo900 UG will not provide. We rely on community providing the OS for Neo900 hardware.

Both shall be roughly in same ballpark. There are factors that act in favor of neo900, but others act against it. In the end the difference shall be negligible.

My experience with N900 battery standby time is like ">1 week with active ssh session via WLAN". I think that's good enough. We can't simply change the type of battery, there's a bay in N900 case the batt cell needs to fit into. When your battery standby times are disappointing, check your active apps and usage pattern and compare to arbitrary other smartphones under same test conditions. The N900 (as well as Neo900) usually shall win any such competition, given the apps are actually doing exactly same. Finally you're free to opt for a Mugen-alike battery (larger formfactor) with augmented capacity.

yes. Though quality should be slightly better than N900. Plus we look into supporting digital-video-out adapter via USB port (http://www.displaylink.com/)

See above. And we won't provide own software, I think there's linux drivers readily available, though I didn't check a real physical setup yet.

I have an N97 collecting massive dust. I can gladly give it away if it would be of any help.

We hope for implementig this SIM multiplexing in a way so that a possible future modem firmware upgrade might support it. So far we heard no details from Cinterion/Gemalto regarding this, so we neither know if such firmware upgrade ever will come, nor can we do better than just guessing how we best interface the multiplexer to the modem. We also need to check certification situation which maybe introduces restrictions what can be done to the SIM interface.
We're not really considering to place a second modem module in for "Dual Talk" (DSFA)

Simple bottomline: we would like to get true dual SIM, but for now modem support is missing for that. We might be able to offer electronic SIM swapping (only one of both SIM active at any time. IOW you're not available on two numbers concurrently)

cheers

*) don't ask me what happened to the recent version of this wikipage, it seems somebody removed a lot of useful info, thus this link is to an archived version
I'm wondering if there is any update on the dual sim since last June, or if the above is still valid...

If you have done any training than you will have zero problems. N900 is very "friendly" when it comes to disassembling/reassembling. Particulary for a slider device. Nothing is glued, no hidden plastic latches that will broke, it's a pleasure to work on it. Unlike SE zylo that I was replacing LCD ribbon recently

Alas no changes. Then OTOH I had no chances yet to talk to the Cinterion guys myself, Nik did that. So if there's some progress whatsoever internally to Cinterion, I wouldn't know about it.
