couldnt have said it better myself...
the tricky thing to remeber/know is which apps are using data and for what purpose... Im sure initially you were thinking you shouldnt be charge data for the apps you mentioned, but like mike said something as subtle as Swcked moble shell, cant bite you in the ass because it is using data to update your weater... very subtle but can be costly... So keep that in mind, in the meantime until you get yourself a nice data plan!
