I have two problems with my stock DInc after receiving a SD Card error last night. Unfortunately I didn't think much of it at the time and dismissed it. Now neither of my SD cards are recognized. With either one inserted Total and Available space are "Unavailable" and Mount and Format are greyed out. When I mount the phone to my computer the phone memory pops up along with what Win7 thinks is a CD drive. I don't have a reader to use at the moment, but I'll be picking one up tomorrow.
The other issue is that Wifi will not turn on. Whenever I click it in Wireless & networks it says "Turning on.." and then comes back with "Error".
