if u want to install SBSetting, u have to jailbreak ur iphone first. then a CYDIA icon will show up on ur iphone, get in and searching for SBSetting, install it. then slide the time (on top of ur iphone screen, cos it won't have any icon show out on the spring board), SBSetting will show out. then u can manage ur data, edge, 3g, wifi...on or off. if want to escape from reducing ur 3g cost, then u have to turn off data and edge. it will stop reduce ur credit from ur phone. ^^
