I am not sure what may be causing it, but I log in to my facebook and twitter accounts and set them to sync with my contacts. If I go into settings/accounts, they are listed there. I use TweetDeck on a daily basis to check these accounts, but occasionally want to use the native apps. It seems like after a day or 2, the accounts disappear and I am forced to re-login or re-add them in the accounts screen. Anybody having anythign similar happening? Can someone with TweetDeck and BB verify that they're facebook and twitter accounts are staying intact? Thanks.
