This was the update they recieved on friday last.
Based on what I've read, that's a misunderstanding on their part. But again, if need be, I will push again. I'm just taking a patient, fact-based approach. It works better in the long run than hysterics in my experience.

It reminds me of the N95 slider issues, although those could be fixed at home.
Yes I would advise fixing the pins on your charger to reduce the stress on the port now you have it back. There are a number of posts on this thread advicing how to do it.

Texrat - It might be worthwhile to give them a push in the right direction and suggest that a rep should visit this N900 users forum to get a first hand result of their ineffective internal communication.

Also, an update has to be issued that this problem has been fixed for the new production units since swapping to new units will not fix the design flaw.

i also too have heard that if pads are damaged that cause the port to pop out, nokia wont acknowledge warranty (as i posted earlier).

if the soldering part is the other problem, why does it only have an issue with the n900? I dont get it, i have devices with the same microUSB port but no problems were issued. what kind of soldering iron or....however you call that is used in other devices which give the exception on n900?

I dont really know about the pads do, but what i know is when pads are damaged, there is a problem connecting the charger or cable even if the microUSB port is still attached.

Oh come now I am not hysterical. Just pissed.

We are both saying the same thing. Wait and see. The only difference is I am less trusting of Nokia then yourself atm.

But your last statement about all the devices with removed ports (rather then loose one) likly being pad damage makes sence based on the repair update I saw.

So you have made me feel better about it.

I wasn't calling you hysterical, just saying.

FYI if I'm going to accuse someone of anything I will be much more specific than that.

There is no soldering iron. There is no way to get one into that spot even. Rather, high-volume processes like wave or flow soldering are used.

These processes tend to be so robust that soldering defects very rarely occur. As for the pad removal-- I'm betting a PCB surface preparation problem. Copper lands should not come off, either... even under stress.

the PCB? hmmmm....not fully understand but a bit clear to me.

I usually take my old devices to some professionals when its out of warranty period. almost all of them said that my devices caused to be faulty because the PCB is damaged (someone said burnt). and all cases are in terms of hardware. usually, the issues of my old phones are not charging, not rebooting properly, NOKIA Screen of Death (in one case).

PCB burning can be caused by different things, but usually a short circuit or capacitor failure. The latter is extremely common, especially in power supplies, typically caused by bad capacitors ( a global quality problem right now-- I have replaced bad capacitors in my TV and refrigerator and there are numerous reports of how big/bad this is) and/or bad design decisions (erring to low end in capacitor value, rating, etc). Both of these problems are driven by the mad race to get things cheaper-- although African "politics" also plays a huge role in bad capacitors.

awright......when i saw the internals of the n900 here, i got the idea of the battery issue (only a 1320mah instead of a stronger one) and accepted. on the pictures, there is an x mark on the usb port, what can you say? or that picture does not tell us anything about this issue?
