As said, you can't. Download blade checker from market. If it says you phone is a GEN1 or GEN2, proceed with the app TPT helper and partition with 180 mb system (to be on the safe side) and the rest for data. However be very careful when doing a TPT as it may brick the phone if you screw up. Do your research and check everything twice before you commit.
noob question can i flash with system 138 data 315 and cache 2 please, if not how can i change it.
