IT might be worth adding one thing to your instructions. Before applying the epoxy wipe the usb connector and surrounding PCB area with an ear bud soaked in ethanol (alcohol) or acetone (nail polish remover). This will remove any flux that may still exist on the board from manufacture and ensure a better bond for the epoxy.
It might also be a good idea to try somehow cover the holes in the USB socket to ensure that epoxy does not get into it and prevent the plug from being inserted cleanly. I have been trying to think of a way to acomplish this. One ide is to use very small pieces of blue-tac (http://en.wikipedia.org/wiki/Blu-Tack) since if these get through to the internal connecter they should be harmless and probably come out with the plug next time it is removed.
I intend to do this mod to my N900 this weekend. As they say prevention is better than cure.

Many of us, especially with no experience in hardware modding have no courage to open their 500 euro phone just to make sure it doesn't break. I rather risk my USB port breaking and then returning it to nokia for repairs than void my warranty. Of course it is different in your case as you didn't have the warranty in the first place.
Then again, I have some experience repairing laptops, so that helped. The main rule to follow is that nothing should take a lot of force to take apart.

I have a DDP device so I'm without a warranty and thus extremely concerned about a possible future break of the USB port. I'm also an electronics engineer. Despite this, I'm very hesitant to dismantle my N900 so that I could epoxy the USB port. I did watch the original disassembly video that was posted on a gadget site a while back, but I simply don't feel comfortable with disassembling/re-assembling small devices like the N900. Give me an old TV any day though..

You did this instead of using the epoxy; You did this without opening the phone;

Why not use epoxy between the plastic cover around it and the usb port just for preventative measure?I was thinking about it the other day.This way it will held for longer.

Even if you considered filling up that space with epoxy, you need to be careful not to cover up the hole for the LCD screw, while building it up high enough to reach the USB port. And epoxy dries up extremely fast, becoming brittle if you try to remould it. But once it cures, usually within 24h, it can be sanded down as reshaped that way.
If someone can come up with a way to do it though, I'd like to hear it.

I actually had a thread on this a month or so ago, but the chief holdup for me was that I would void the warranty in the event that some other issue were to pop up. Now, if this machine makes it past the end of my warranty period (one year, U.S. -- as I understand it), then it is the first thing I will do. Probably that day. Watching the assembly, dis-assembly video shows that technically it is really not all that challenging. Glad to see you have done it, though. Gives me hope when the time comes.

My solution
i don't want to wait and i fix this in advance . put some epoxy between secondary board and usb socket have placebo efect because secondary board is fixed with dual face adhesive sponge .
Advice . protect camera lens when solder

Some forum members were also passing around the authorized Nokia disassembly guide, so it's good to know an experienced person such as yourself has done this successfully. That means there is hope for my meat head and sausage fingers to fix mine should it ever break again.
Thanks!
