Ok I get ur directions but I don't understand a thing. So, what is 'cid'? why do I have to unlock it? Do I need a memory card for this? (now dont laugh @ my next Q's

what's a 'rom'? what does it do? what do u suggest I use? which 'olipro v7' do I use? what is 'olipro'? And why am I doing all this? I'm sorry for all the questions but I wana know what I'm doing to my phone before I do it. Thank you for getting back to me so quickly

I hope I'm not too much of a nuisance.
