Hehe.. well , this my kind of topic . On tuesday(17:th) morning there is exciting news from nokia. Keep cool ;-)
About the numbering of nokia, your theory is not true.
The naming of nokia phone have to do with the segment the phone is targeting. 6XXX are business for example, 3XXX are youth.
Regarding the 3300 and/or N-gage.
I have the N-gage my self sine a few month back. It a really good phone, with all of you required features and then some. Comes with 64 meg memory , thats used for games/ mp3s or what ever.
Since you also are on this forum, I bet you like games ? Hold out until october and get an N-gage instead of the 3300. For sure !
