1. What does this have to do with Neo900? Please learn to observe the thread's topic. Posting your questions in random threads is generally frown upon.
2. Check your car charger's USB connector. I have three car chargers. All of them work but the connection is rather temperamental. So far I had the best results with the cheapest one from Poundland. which has a USB A female connector instead of a cable sticking out, coupled with a cable that I know works on a PC.

For Neo900 we will provide battery charging pads under the back cover (when we can find a way to do so), and we will take care to make them as tolerant to crappy supply as reasonably possible.
For USB we need to follow the common USB2.0 & charging_amendment specs, and we will probably use the same detection scheme like N900 (D+/- short), since it's the simplest (for user to handle) of the 3 variants for fastcharger detection that the USB specs define (the other two involve resistors to get soldered to the plug, sth you don't want to do). Anyway we will take care that charging is controllable by software just like it is on N900.
Please check other threads in this forum about fastcharger detection and D+/-_short

Here at 1:52 [1] it looks not trivial but quite doable to remove the dome sheet. However the next slide in the video says: "Do not use the domesheet again."
I'd like to understand the reason.
Of course reassembly might be a completely different story than disassembly which is why I usually don't like disassembly guides that end by simply stating: "to reassemble just follow these steps in reverse order."

I suspect the problem is with the "play dead" state of the phone, as most decent chargers alter their state based upon what's plugged in...and so does the N900, so they cancel each other out once the N900 boots past the hardware charging state. Every other device I have works with my chargers just fine...

...but yeah, if the Neo900 could be more robust, that'd be great

I'm pretty sure you already know this, gerry-mobilfunk.de seems to have domesheets. [1]
I have no idea what happens if you input a 3- or 4-digit number into the quantity field. I'd like to see Gerry's/Thomas' face though.
Maybe he knows some secret supplier. At least asking him wouldn't hurt.

Re: Neo900 - finally a successor of N900
So what audio chip has been picked for the Neo900? Same tlv320aic34 as N900?
Yes :-)
cheers
/j
off of four inputs if I read the spec sheet right.
Maybe I need more coffee,
but maybe someone out there knows if it can ?
If so - I would assume (don't get distracted here)
we would have a normal stereo/mic jack for line input
and have an embedded mic (1 or 2 ?)
for the audio input ?
just curious,
it gives me some ideas for later on down the road....

the article is usually available from stock in qty of 3 - 8 max. We don't have info about amount available from Nokia
