Hi, I currently use the i860, i would like to upgrade to the i1 or a blackberry. With my current plan I have unlimited data access on an old internet plan. My question / problem is Sprint tells me that to use the newer internet capeable phones I have to change my internet pkg. to the enhanced pkg I belive,which would result in a big increase in my bill. Anyone know if they are feeding me bull and if I could just switch sim cards and be ok? I don't really need any better internet than I already have.
