sd card mount is not working atm so backing up won't workTiBU may not work, but MyBackup Root or MyBackup Pro may be a usefull fall-back if you're backing up your apps.
Put anything you may need in cminstall before starting the install - e.g., the CM9 update zip, gapps zip, CWM zip, moboot 3.5 zip.
Wifi File Explorer or Airdroid are nice alternatives to move files around if you are having problems connecting via USB after installing.
The program Nova Launcher is the BEST launcher on ICS...get it from XDA forums:
Does anyone know if the Gapps that we have been using on the Samsung Galaxy Nexus with CM9 (and plain AOSP) Kangs would not work on the TP? Since they are proven to work w/CM9 Kangs on the Nexus, thinking that they could work w/the TP as well...
