I got me a N800 a couple of months ago, and I'm loving it. Now my mobile phone has died, and I need a new one. My only major requirements for it is 3G and wlan, but of course, it should have some kind of mp3 player, the basic web-surfing capabilities etc. However, this phone will most of the time be used together with the N800, and though I'm not on an extremely tight budget, I wouldn't want to spend way much more than I need. So what reasonable phone can I get that doesn't "overlap" too much with the N800? (I prefer Nokia or Sony Ericsson, but I am open to try new products)
