Last night I was trying to update an app (Angry Birds from Amazon Appstore), had some issues with it not installing correctly. Upon direction from Amazon Tech Support I updated my Amazon software to the most recent version, still no luck so I turned the phone off and then back on. Upon rebooting, the phone froze up as it was initializing the SD card. Repeated attempts were unsuccessful. If I remove the SD Card, the phone will start up fine and work normally, with the exception of that missing data of course. I'm not sure if its relevant, but I was close to maxing out the 8gb SD card. I deleted a few files/etc and there should have been about 300mb free. Could that have anything to do with this? AFAIK, the app update was downloaded to my phone (onto the SD Card) but it would not install. The SD card is working normally, I can plug it into my card reader and it works fine. Any ideas? Thanks.
