I have a stock Bionic running .905 from the OTA update. Rooted it today to create a Nandroid backup, and have copied the backup off the phone.
If I follow these steps, will my installed Apps (and their settings), along with my SMS messages/history, and Call Log be preserved after the upgrade to ICS?
If I'm running stock .905 (other than root), is there a shortcut version of the install that'll avoid the steps to revert to .902 then re-apply the .905 update (i.e., do I have to download the whole thing for parts I suspect I don't need to revert?)
If my apps won't make the transition from .905 to ICS with this script, is there a best practice/easy way to re-install them?
If something goes wrong, I assume the recovery process is to get RDSLite and go back to the 902 FXZ, then OTA update to 905 again, then try and restore my Nandroid backup?
Thanks for the info.
