I am having a replacment D2 sent to me because my current D2 is having major SD card issues. I tried formatting the SD card and it works fine on Windows, but now it won't even mount to my D2. Anyhow, I was wondering if I should worry about unrooting my phone and flashing it back to a stock ROM.....I mean my guess is that since this is most likely a hardware issue, they (Verizon) will probably wipe the phone anyhow. The phone that is being returned is currently on Liberty GB v0.8. Any advice on this?
