So, like the title says, I'm having some issues... DX, running GB 573, no OC. For a bit the phone has been acting "off". Random slowdowns. Several force quits. Last night I tried to copy a file from the computer to the phone and it took a long time. Late last night I get the "SD Card is Blank or Unsupported Format". Reseated the card, nothing...tried to format the card in the phone...nada. Came home and tried to read the card directly on my computer...nope. Replaced the stock 16gb card with a spare 4gb, and the phone feels faster, but I'm still getting force quits (especially with ADW launcher). Anything else I can do to see if my phone is dying or just have a bad install of something?? I mean, the stock card is already fried, I don't want to fry more.
