I really want to JB my ip4, but Ive read it drains way more battery. Im just wondering if some of you could let me know how much of a difference if any you have seen on your battery since JB. I really only want to run T-lert, SBS-settings, lock info, activator, & pdanet. Also back on my 3g i purchased Lock Info, though Im not sure how I can transfer over my puchase to my ip4 without having to pay for it again, I believe i bought it from cyndia, but i really cant remember. I would rather not open ssh, so what should i do? Thanks!
