I'd expect it to get fast when you leave the building, and back to
slow when you re-enter. It all depends how good 3G coverage is, but
seeing it change more than once a minute is not that uncommon.

Event... not sure. Linux can ask for current signal strength, and I
assume connection type works in similar way...
