I got my G1 about a month ago, and the SD card that came in the phone when I bought it has corrupted about 4 or 5 times now. Usually, formatting it will do the job and it's up and working again. But now, formating it doesn't do anything. I called Tmobile and they connected me to HTC, who makes the phone, and they said they are sending me a new SD card. It seems every time I plug it into my computer and put pictures on it from my computer it will corrupt a couple days later. Can I only keep pictures that I actually take with the phone on it? And strangly enough, every EXCEPT my music gets corrupted. What the hell is going on here?
