I didn't see the edit, no. Yes, assuming you can get into recovery. You may have to RUU back to stock, though.

Ouch on the price. I just saw the exact same thing for $60 a couple days ago. How long have you had it? And TopData is a lower-end brand, from what I've seen.

If you want you can get a 16GB card for around $20, but you're talking class 2. Class 6 I've only priced 8GB and that was about $10.
