If you want to go back to the sense ROM by laibo that you tried but did not have facebook and twitter for htc. You can actually pull the .apk files from a different rom and add it to system/app while on that rom. This will add facebook and twiitter and you will be able to use it through friendstream widget aswell. Message me back if you need help. The two apk's you will need are htcfacebook.apk and htctwitter.apk after that is done simple go into settings, acounts and sync, add account and log in to both of those accounts.
Double check that you have a friendstream apk as well in there already.
