Root Tweaker allows you to easily apply the most common tweaks for ROMS, such as the apns-conf.xml from Cyanogenmod for automatic APN configuration worldwide, the hosts file that includes almost all add providers, thus blocking all the adds. And a patched gps.conf with AGPS for optimal GPS performance.
Additionally I added some init.d scripts, it's advised only to install these if you know what you're doing!
Root is required!
WARNING TO ALL NOOBS:
Stop flashing apns-conf.xml if you don't know what It is... If your data connection works why would you flash it?
It's only for phones that have no APN configuration so far.
To restore just download a custom rom from XDA-Developers and pick the /system/etc/apns-conf.xml file from there..
