After getting HC running on the SD card one of my first app installs was a twitter client. It worked perfectly without any problems for a day or so, then I noticed it stopped updating. I tried another twitter client and it would not allow me to log into the account. I uninstalled the original client and reinstalled it, now it fails to log in as well. I have went multiple times into my actual twitter account and changed the password and re-attempted to log in with a twitter app but they always say the account is invalid or failed. Strangely enough I can use the nook to open the twitter.com page and log in that way, but its not really optimal. Any suggestions other than wiping the card and starting over *bleh*
