Funny, I got so used to setting date/time after swapping batteries that I assumed this had always be the case.
However, since the n900 is still my main phone (I'd like to keep it like this for the next couple of years to come) and I don't trust my soldering skills, I'm not going to attempt a hardware fix. But thanks for sharing this information with the community.

good post.
For those considering doing the soldering themself, you should be aware of RoHS. (http://en.m.wikipedia.org/wiki/Restr...nces_Directive)
Shortly, you need higher temperature when soldering this, than with usual lead.
going to ask a good friend myself

All times are GMT. The time now is 16:01.
Now for the "bright" side of this story: the battery is easily replaceable when you got some moderate soldering skills (and tools), and using a
YUDEN, PAS414HR-VA5R, capacitor, 0.06F, 3.3V, STAKED COIN Coin Type Polyacene Capacitor https://hbe-shop.de/Art-2112777-TAIY...3V-STAKED-COIN will avoid having it broken again in another 12 months of time. (datasheet)
[edit]my local stock of those ran out, so the following doesn't apply anymore[/edit]
For your convenience I got some of those components as of above, and I'm willing to ship them worldwide via simple letter, for a 3EUR donation per unit to maemo donation paypal account. Contact me via IRC(freenode.net):#maemo or by mail to techstaff at maemo.org, or simply donate and give FULL addr plus your online contact (mail or IRC) in "message to account owner"
some macro-shots (taken with N900):
cheers
