I like many have have ICS .211, Titanium backup, OTA rootkeeper and free wifi tether hack thru SQLlite as well.
I keep getting the request to OTA update, so I froze the updater with TB for now but want to do the upgrade if it is safe.
How can those of us with this config;
Safely upgrade to JB
Keep USB & wifi tether
Also will it be ok to restore all user AND system apps with TB after upgrade?
There are a hundred fragmented threads but I cannot seem to find the surefire way to do this properly.
