Samsung SCH-i760

Hi all. Is it possible to cut my data plan (I currently have the unlimited $99 a month package with unlimited text and data) and just go with a regular plan, get a text/pix package and pay as I go on data? I really want to not pay $108 a month for this anymore - last month I only used 2 megs of data anyways and since this phone has wi-fi, I don't really need data too much, only sometimes.

Any suggestions, and pricing info? The web site makes it difficult to tell what works on data phones...

Thanks!
