I'm about to switch to cingular and am wondering if here in fort myers, fl I should spend some money and get an HSDPA phone or stick with an EDGE phone for free(w/rebates and contract). If there is a significant difference in speed I will definately get either the 8525 or the treo 750, but if not I will stick with a treo 680. Does anyone in my area have any experience to share? Thanks.
