Re: sd card damaged?
How do you know it's damaged? Often times there is a switch to lock the SD card from being written to. Check to see if that switch is there and if it's locked. If it's truly locked you'll need to return it or purchase a new one. You can also test the hardware of the phone by installing another and seeing if it works. If it doesn't, it could be a hardware issue with the phone.
Let us know how things go.
