I had halfcab 123 root my Thunderbolt and installed BASF ROM with Sense 3.5
Rooting great / Rom is fast and smooth / like most ROMs - some bugs
It reboots itself once and awhile
Occassionally phone rings and green accept button not present
wireless tethering works great
there service is good - you can flash any rom you like better - like MIUI Rom by Vicious
