I am hopefully unlocking an iPhone next week but have a few questions first. 1. What would you recommend: ZiPhone or iJailBreak? I am leaning towards iJailBreak because it looks easier to use. Also, doesn't ZiPhone downlgrade the bootloader or baseband or something like that? 2. If I used iJailBreak (or ZiPhone) and it went wrong, what would I do and would I be able to use ZiPhone, say if it did go wrong with iJailBreak and vice versa. 3. I have seen that people say I should install BSD Subsystem and Open SSH. I don't plan on using the installer, in fact, is there any way to delete it? Are BSD Subsystem and Open SSH necessary if I don't want to install stuff with Installer? 4. I have seen varied reports. Some say I need to put my desired SIM card in before unlocking. Some say I don't. What is the best thing to do? 5. The iPhone I will hopefully be unlocking will be an out of the box 16 GB version. What exactly should I do if I used ZiPhone or iJailBreak? Do I need to turn the iPhone on for the first time and connect, turn it on turn it off, do anything in iTunes or put into recovery mode or DFU mode? If so how do I do that? Thank you from a (hopefully) new iPhone owner needing some help!
