I traded in a Nokia phone for the KRZR a few weeks ago. The KRZR doesn't drop as many calls as the Nokia, but in the areas where the Nokia typically dropped calls, the sound quality on the KRZR is terrible. At least it's better than having the call dropped.The KRZR synchronized over bluetooth using iSync on my Macintosh without any trouble at all, so I was happy about that. I also bought a 2Gb SD card for it which I was able to load songs onto over bluetooth so I didn't need to buy a USB cable or SD reader.The Nokia had a nice feature where I could set the phone to beep once when it rang. This was good in meetings. Haven't figured out how to make this work on the KRZR yet.This phone is advertised as an MP3 player, but the adapter to connect regular headphones to it is not included. I see that I can order it from Amazon for abou $5, but none of the cingular stores I've gone to have it.A slightly annoying thing about the phone is that no games come with it. Or I should say, all the games are just trial versions which let you play for a minute and then ask you to buy the upgrade. I don't have a data plan with Cingular, so I have no idea how much it would actually cost to download games or music from Cingular since I believe you pay buy the byte when you don't have a plan.
