I've recently upgraded to a k800i; 3g, compared to my k750i 2g handset.
They sent a 3G sim-card, but I'm happily using my 2G sim-card in it at the
minute. Do 3g sim-cards offer any benefits, excluding the obvious higher
bandwidth? I was planning on getting it activated, and using it in the
phone, with 3g switched off. Even with this switched off, is there any
reason for it to use more power?
I'd expect the answer would be: no extra benefits, uses same power; but you
never know these days!
