I'm with Sprint and I'm thinking about getting the Diamond. If I order a new phone on an addtional line I will get discounts and rebate. What happens if I don't like the phone and want to return it for another like the Touch Pro? Will the discounts and rebates carry over. How does the exchange process work? Will I be without for awhile? No Sprint stores here. I will have to do the transactions online or more likely by calling. Thanks for any info.
