Restore specific items using Titanium Backup without root? I regularly backup my entire phone using Titanium Backup. 

For the next two weeks or so, im going to be using my friends phone. Id like to restore a few things from the backup (contacts, some app data etc.) without rooting it. Is there any way?
Titanium stores the .apk's in /sdcard/TitaniumBackup/ and the data in the same folder in zip files.  You can click the .apk to install it when viewing in a file manager.

To restore the data, you can extract the zip file on a PC and copy the contents of the data folder (another folder named something like com.domain.appname) to /data/data/ on the device using adb:

adb push com.domain.appname /data/data/
