would it be compulsory to subscribe to data plan to use sgs? i'm a bit reluctant to switch my package now since most of the places i went to usually have free wifi..would there be data transfer going in the background whilst using this phone that might get me charged w/o realizing it?

thanks for the prompt replies guys i think i might stick to my plan and see how it goes first.. can't wait to join the league of sgs users

now that my fren, is a POISON!!!

been a week with my sgs..so in love with it sampai tak sempat read all post here still on stock 2.1 ..dunno how more interesting it'll get after root and flash later. heheh
