I took my (2 week old!) N900 into the my local Nokia service centre and they said they could do it right there in 30 minutes, depending on how broken it is. Mine turned out to be more broken than they could do, so it will have to go back to Nokia, but it's freepost and you literally fill out the form.
Apparently it was on a Nokia bulletin in the last few days.
I asked about recalls and if anything is going to be done to stop this happening again and they said Nokia isn't just replacing that part. Apparently they've supplied a better designed connector which is being fitted instead.
I'm not totally sure what needs to be not broken for the service centres to fix it.
As annoying as it is having to send it away, I'm quite relieved that I'm not having to fight them as some people seem to.

See, a much more reasonable explanation of the situation (rather than assuming Nokia made some changes that cannot be determined with the naked eye) is that Nokia did not change anything at all except their press releases. Not unlike Toyota removing floor mats I suppose.
I want to see pictures of new units that either use through mounted USB ports (highly unlikely since it requires a motherboard redesign) OR much larger solder pads OR a new plastic casing design that provides support for the USB port. That's when I'll believe Nokia did something about it.
Improving the technique for surface mounting the USB port won't help one bit if somehow the USB cable gets snagged and pulls sideways or downwards, or if the user tries to insert it upside down or is simply a butter fingers that cannot correctly align it with the port.
what do you think are the changes (hopefully) will nokia make?
if they will only add an amount of soldering iron, why did they not do that in the first place? or doing that may result into something?
and if changes occur, will they assure that this issue will not be present?
Sorry for a lot of questions,

It seems more appropriate to say that the problem is dependence on adhesives rather than using poor ones. It's better to hold something down from the top than from the bottom.

hello all.
i just bought my n900 today and am very excited to have it however i am curious if this usb problem is affecting ALL builds or are there specific units affected?
how do i know if mine is affected?
if it is affected shall i attempt the Do it yourself method considering theres hardly a dependable repair store in baghdad.
pls advise.

To the best of my knowledge, there is no official word on what builds are affected, if there will be a recall, or even if Nokia has actually addressed the problem in current design. I read a couple pages back that a care employee stated that Nokia improved the design but they've been saying a lot of things. I'm very interested in this particular bit of information and am waiting for word on it so I can plan for how to spend the money I have set aside for a device such as this.
There's also no data on whether the DIY fix will improve the integrity but I think it probably will. Just be absolutely sure you don't get epoxy inside the plug body itself or it will be just as unusable as if it had fallen off.
If there's no way to get your warranty serviced, there's no reason not to give it a shot if you're confident with electronics. If I didn't have a warranty, I would have done that myself but a voided warranty and a broken device wasn't my dream come true.
EDIT: The wiki also says that the DIY "may" void your warranty but I think given that charging the device voids your warranty, we can assume that squirting epoxy sufficient to fix this design fault *will* void your warranty as well, no?

I looked a bit around what MicroUSB connectors are available. Surprisingly most I found are pure SMT types, but I did find couple with two or more through hole posts here and here.
Considering N810, it seems it does have different different connector. At least the plastics color is lighter and the shape is slightly different. (Type AB on N810 while Type B on N900?) I have not heard anyone having problems with the N810 USB connector. Anyone knows if that particular connector does have through hole posts?
How about the other new Nokia phones? Like N97, etc... that supposedly use the same USB connector?
I compared the supplied USB cables I got with N810 and N900. They are both exactly the same (CA-101). Insertion and removal forces felt about the same on both N810 and N900.
Having some through hole pins is not a problem to use in pure SMT lines: In my company we do have many "hybrid" board design with both through hole and SMT components. We call it PIH (Paste In Hole) process, where through hole parts are soldered in place using standard paste and reflow process. It works fine and it does not require any special machinery. The same pick and place machines can place these through hole parts just fine. This is as long as there is smooth top surface for vacuum nozzles to pick the parts from feeder. (I don't see the these USB connectors being any different in this regard.)
Hopefully Nokia can start using new part in their new producs. Even on N900 I do not think it would take serious PWB redesign. At that location close to the board edge I do not think there are much, if any signal tracks that needs to be moved avay from the mounting holes. This shouldn't affect any certification (FCC, CE, ...I think?) either, so it should be pretty quick and painless process. No?

From our experience any change that requires a new spin on the PCB (yes even if all you do is add holes instead of pads) will be regarded as a new hardware for certification purposes and would need a full compliment of tests done - from ECC right through to safety. While is would not be terribly expensive I would not say that is is in any way quick and painless.
We (set top box manufacturer) try our hardest to avoid hardware re-spins for this very reason - often it is cheaper to have a person on the assembly line do a wire mod then re-spin and re-qualify a . Obviously in this case a wire mod would not do
