Ya know I had a heck of a time with Hotmail beginning late last night through this morning. I ended up doing a factory reset and it worked itself out

 

I'm having the same problem. I posted this on a few diff. sites, in hopes someone'll know what to do.

'Anyone else having issues with FB widget on BIONIC? Says 'Facebook sync failure. Incorrect username or password.' Funny thing is, the FB app works just fine. For some reason, the widget doesnt. I tried going into 'Accounts' to remove/add FB, but it gives me the same error. <-- Says un or pw is incorrect, but the username field is grayed out and you can't edit it. Even tried force stop and clearing data, but still no dice. HALP!'

*I wonder if it has anything to do with my old phone (DX) still having the account/widget setup. I've been using it on occasion while connected to WiFi for random purposes...

 

Ended up doin' a factory reset. Seemed to have resolved the issue...
