yes, disable the data connection... BTW better to take a plan if you wanna have data connection on always... i'm using maxis data plan and until now i only used up about 50% of my 500mb allocation and i still have 10 days to go... the things i sync on the go always... gmail, company email, weather... i also surf and download apps using data connection... no problem at all... close all the friendster, facebook, twitter sync... that will help a lot... btw i did not use them often so i duno whether it take up a lot of data or not...
