oh my god ..... it was like i have this c380 a couple of months ago and now ...this c390 spring out ... included with the bluetooth capability ...a really good features i didn't really often see in normal class phones. c380 relatively work well with it's performance , but the production of c390 however i think it's a waste .Motorola only imbued the bluetooth capability only and also the e-mail messaging. the rest are the same.The cover for c390 is identical to c380 and the color of cover can be fit in to c380 to ..What a waste motorola did. They should upgraded the memory of 1.8mb to more memory of make and extension slot for more capacity. However the motorola didn't and that was a very big dissapoinment to me and maybe to you to . c390 has only this 2 new features that i can see .The design are still the same , dull and boring . Altough it's circular navigation key and it's keypad looks relatively nice and easy to press , i'm sure those who have the c380 aren't gonna get this c390 for it's quite a boring design . But overall c390 and c380 are brothers but only the additional 2 new features are added in the c390 ..
