i know their are guides out their but my question is more specific. Im wondering about the kernals.... "-600Mhz LV 5X *Already Included* -800Mhz LV 7X -1Ghz LV 7X -1.1Ghz LV 7X -1.1Ghz SV 7X -1.2Ghz LV 7X -1.2Ghz IV 7X -1.3Ghz LV 7X -1.3Ghz IV 7X " Whats the difference between LV and IV? ive got bb 1.1 -1.2 iv 7x(Lv is not available in rom manager) and just am wondering if one is smoother than the other? im going after battery life, so thats the deciding facter. also i found a link to a p3 site thats got alot of kernals also, would any of those be better? im kinda new to Oc-ing so thats why im a tad confused... btw if i do decide to change my kernal can i just overwrite the current one? or am i going to have to do a data wipe and such....?
