Hello people,

I just bought a Nokia N900 (march 11th 2012), and after reading the forums for a while I decided to do the preventive USB soldering that Dr. Frost is recommending.
But after opening it, it looks like this is already being done for new phones.

See the pictures below, there is a solder drop on the right side, but none on the left side. Probably because the left side would require to cut some plastic.

I don't know if I should do some soldering on the left side as well, any recommendations? I don't feel so confident cutting the plastic, is it really needed?
