Mine fried tonight. Phone just sitting on table...then started beeping. When I looked it said SD card file system not recognized...do you want to format. I didn't want to loose all on the card so I did not format. Took card out of phone and tried to read on computer. This did not work.
Called VZ tech support. Told him what went wrong....Didn't hesitate for a second and offered a new SD card. There must be problems with the SD cards...this was too easy to get a replacement and not have to send the old one back.
