Ok guys so I got about 10 OTB 1.1.3 iPhones in front of me (2 of them are the 16 GB version). I was wondering what would be the best way to unlock them completely to be used with any sime card? I have seen two different SW unlock methods. Also these questions are also killing me:

1) Ideally I would want all of these phones to remain at 1.1.3 and be SW unlocked is that possible at all? Which website/method do you recommend?
2) Would the same method work for the 16GB iphone as well?
3) I heard a few weeks earlier someone talking about 1.1.3 OTB having a new Bootloader (not 4.6) is that true? Most of the new SW unlock method is for a 4.6 bootloader would that work for an OTB phone too?

I guess i am just waiting for an expert confirmation before i can get to work

So please any input is really appreciated! Thanks!
