I've searched long and hard online to find a solution to this problem with no answer. I have a droid x. Listen to podcasts on acast app. Worked fine for many months, but I think after the most recent os upgrade (2.3) I was no longer able to download podcasts. When I try, I get an error "read only file system". I get this same error with other podcast apps as well. I've also noticed that I'll get this error now when trying to back up my apps and files on the droid. Any help is appreciated. Thanks.
