So, I'm new here, and in need of some guidance. Hours of internet research have not confirmed my ideas as yet. It's time for some serious assistance:
I have an iPhone 4 on 4.2.1 BB 03.10.01. This baseband remains unlockable, as far as I can tell.
I would like to get this phone on ios 5.0.1, jailbreak it, then unlock it using Ultrasnow.
I believe I need to create a custom firmware to retain an unlockable baseband before I update to ios 5. How do I get an ios 5.0.1 unlockable baseband (01.59.00, 04.26.08, 05.11.07, 05.13.01, 05.12.01, 06.15.00) on this phone? I am not keen on using 06.15.00 as this is not my own phone and I know from personal experience that 06.15 can be problematic for future updates, etc.
Can I still update the iphone to 4.3.3, then create custom firmware to retain the unlockable baseband? Or have Apple stopped signing for 4.3.3? If so, can I use tinyumbrella to bypass that problem? This phone has no SHSHs saved and has never (as far as I can tell) been previously unlocked.
Does anyone have any other suggestions?
My main question is, which ios can I update to before I create a custom firmware for ios 5.0.1?
If all else fails, can I still update to 5.0.1 then flash with the iPad baseband (06.15.00), or will this cause monstrous problems?
Happy New Year to you all,
