go to the OS forum on top of the storm forum...
.109 is a leaked OS (not official from verizon)... it will help a lot ... but nothing comes free... as you upgrade to different LEAKED OSs... you will gain some things and lose some things...
but .109 is old already... the leaked .114 came out this week... and an official OS for 9500 (not yours) came out, the .113
there is a thread about a .113/.114 hybrid... that is what i am running... and i am loving it...
hybrid is pretty much mixing both OSs... but DO NOT install .113 alone on your phone... this OS is for the Storm 9500
hope this helps
