I went through 5 Droid 2 devices. Finally after many hours spent on the phone with multiple supervisors, they sent me a brand new Droid X. I want to keep my old SD card but will this cause problems since this is a completely different phone model? Also, someone told me my SD card might be defective. I told someone from technical support this and they said they have never heard that before. So, do I keep my old SD card (16gb) vs (2gb)? Thank you for any responses! Also, if you suggest I don't keep my old SD card, can I transfer all my information to the new one?
