I am still running 4.91 and its been running fine so I haven't upgraded yet. But today I started getting "download unsuccessful" errors in the market when trying to upgrade or install anything new.
I have tried clearing market data, cache, deleting the android_secure folder and most any other "fix" I could find all with no luck.
I'm a little hesitant to go forward to 5.4 with the market acting tis way because then I wouldn't have any of my programs. Any ideas on what my market issue could be? Do you think going to 5.4 may actually resolve it?
