What? Repair process?
Open N900, look manual. It's in Russian, you can find it in English I think.
Or watch this.
Do steps 1-13.
Open GSM module shield with thin screwdriver (shield is not soldered, it is closed like box).
Then glue some springs and close everything in reverse order.
Some more photos covering my specific steps.

Holly Crap! That worked for me too! Here i used a pen spring, that was easy to cut (2 turns). THANKS A LOT!!!! The sign itīs perfect now (before that, if i put my hands in entire back part of the phone, the signal was lost. Now, not even a single line of the signal is lost . Now to be back to life, my N900 only needs a original digitizer (the ebay one sucks a lot in touch screen) and the 2 screws that i broke
Best Regards,
Germano.

For me, it wasn't software error. When I shaked the phone too hard, about 8-10 seconds after "SIM failure", "CMT reset,,," in logs, etc.
I decided to open the phone. I opened it to motherboard. On the side where battery is, there is cell module (when you remove battery, there is sim card holder and free space with some label, so cell module is behind it).
So, I opened shield around cell module. There are 4 ICs under it. I made something like little springs, glued it to ICs, and closed shield. Shield distended a little.

So, in conclusion, no sim failure after this. Before, if I keep phone in pocket and walk, failure was every 2 minutes.
Problem was even if open slider too fast.
I will write a post later with more photos.
Thanks again.

Very interesting idea for a fix - which, BTW, support theory that reflowing would fix this issue permanently.
I think that it's first "real" solution, after not-entirely-real infamous hammering (literally) pins. I'll try to convince moderators to separate this thread since Forever's post, and make it sticky - after all, they could get some real work, and take little break from banning innocent people

Actually, my phone is breaking again and again, maybe because I added too strong springs, maybe because I opened it too many times, so its body became wobbly (is this right word?).
So I bought another one on ebay, "new" (seems to be "almost" real new).
But it has problem with wifi, when it's on and connected, it becomes warm and eats battery very fast. Does anybody know how to fix this?

When I stripped the heads on a screw under the screen, I remember doing some research and I think I came up with M1.4x2.8 M1.4x5 as the two types used. It was over a year ago when I did the research, it might have come from one of the strip down pdfs.
Anyway, I asked googled around and found a place that sold them, but because I only wanted a few, the guy sent me some as samples. (Unfortunately, the ones he had were M1.4x3, so slightly too long, but they did the job).
I always blamed the contact points of the sim-holder for those telephony errors, but never thought of the chips themselves being the culprit.
Good job, guys.
