Alright, so unfortunately I'm having multiple dropped calls at home, something I've never had issues with using my 3G or 3GS. I'm thinking about getting a replacement, but I'm worried that I might go from one problem to multiple. Has anyone gotten a replacement that was worse than what they started with? Also, has anyone gotten a replacement that wasn't in mint cosmetic condition? Do they let you inspect/try the replacement in the store before you have to commit to it? Made a Genius Bar appt... Hope I'm not just digging myself deeper.
