Questions on capabilty for Ford Sync and hot spot. Currently I have Gzone Boulder which will not pair with the new MyFordTouch Sync and so need a new phone. Looks like IPhone 4 will sync but will need a data plan. We currently use MIFI2200 as a wifi hot spot. Can the Iphone 4 with the 2GB plan serve the same function as the MIFI 2200?
