Here is copy from NRG's tweet about new roms.
"Little changelog for last night's VGA Sense 2.1 ROMs... Updated > Audio Manager Engine, Google Location Service, New Contact Card, Facebook Engine, Contact Utility Engine, Timezone AutoFix, MyPhone app and of course Sense 2.1 CFC
"
so far so good. Tho I do miss the twitter tab. Anybody find a satisfactory fix for this with the 2.1 lite
