So far the phone is great. It's faster than my older Symbian phones, has an application that imports data from your old phone (yay!), has 2 high quality cameras and a logical keypad. (The keypad on my 7610 was a bit too "fashionable".) The main camera has a sliding cover, which I think is a good thing. The only thing I don't like about the design is that it looks a bit like a small Treo.
I just looked at the international coverage information for Japan and it says that the "Voice Rate" is $1.99. I assume this is $1.99 / min. Hmm... Then it says the "Internet Rate" is $1.50. I looked around and haven't been able to figure out what that means. Does that mean $1.50 per packet or something? It's still expensive and I'm not sure if I'll use it much, but at least I know I can. A friend of mine mentioned that if Japan had gone with GSM instead of DoCoMo's funky PDC protocol, Japanese handset manufacturers may have had a better chance competing internationally. As it stands, the foreign markets are dominated by non-Japanese handset companies. Maybe with NTT DoCoMo's announcement that they are going all 3G by the end of the year, we'll see some of the handset guys in Japan start making cooler phones for the global market. On the other hand, I have a feeling that DoCoMo will continue to force the handset guys to cripple their phones. Right now you can't SMS anyone outside of DoCoMo from a DoCoMo phone, even though they are finally using the UMTS standard. According to a friend of mine, this is very difficult to do. You actually have to spend a lot of energy to break the system and limit SMS to your own network.
Here is a matrix comparison of the various Nokia phones. As you can see, only the 6630 and the 6680 do WCDMA 2100 which is the 3G protocol that works in Japan.
The other thing I just noticed is that I was able to navigate bluetooth and the email setup and get all of my data moved over to the new phone in minutes. I thought about how much easier things have gotten, but then I realized that the jargon and the interface were practically the same. I remember only a little while ago when I couldn't make heads or tails of any of this. I was the one who had adapted to the phone. Eek. Lock-in.
