I am having same issue and others, 3 micro sd cards have failed and are now fried becuase of the wildfire, that I now call crappyfire. I also cannot connect to the internet anymore or friend stream and more than half of my applications wont work anymore, scared to spend more money on another (4th) micro sd card as they just keep getting fired. I am very disappointed in the crappyfire as it worked grand for a 3 weeks and slowly became an over priced phone good for only txt msgs and phone calls. The problems just keep coming everyday there is more, and I have not done anythig to the phone in the way of tethering or rooting, just was using as is and it crapped out, that is the new wonderful htc Crappyfire!
