Ok, I dont get one thing... there are several options to update and I dont remember where but I read that one should be very carefull when flashing radio files right? So, could a kind soul explain to me what are the diferences between versions, I mean, stock one has an updated radio file right? So, why would anyone want to update system only without radio update? And isn't it dangerous to meddle with radio files? Is there any kind of compatibility issues? As far as I could grok, system update will change SO, kinda like changing from win98 to win98se right? Radio must be something near bios isn't it? Another doubt is: we can flash recovery only, but what is recovery? As far as I get, recovery is something you use to recover your phone, so why is there lots of recovery options? Amon_RA among other things is something I dont get... I mean, bootloader is one thing, recovery is another thing, flash files and radio are separeted things too.. Well, thanks anyway and sorry to disturb, coming to Android after several years of symbian and nothing else... ps: JIT isn't an option anymore? What happened?
