hum only the 5mpx and 3,5mm jack improved
btw i still prefer the 6600 slide .
but not bad at all
Really great phone and beautiful .but 6600 is old name 6510 or 6520 or 6560
I don;t get on what basis the phone is named. why there are so many 6600s?? do they have something else in common apart from name??
