I currently use GummyJar rom. I would like to try Apex 1.3.1. I notice it says you must be running the 320 leak or the OTA of 340. I dont know if I am running that. This is what my phone says under "about phone" Droid X,2.2.1 android version,BP_C_01.09.07P,Kernel version of 188.8.131.52-g5562e1 w30471@il93lnxdroid08 #1 and build number GummyJar. I dont know what any of that means. Am I running the latest and can I use Apex rom?
