I am planning to update my 1.1.2 iPhone to 1.1.4 and I have a few questions, mainly regarding unlocking. I haven't had to do this before as my O2 non-iPhone sim worked with just jailbreak and activate with 1.1.2, but I have read that this is no longer the case with the newer firmwares.

1) Can I just go from 1.1.2 to 1.1.4 or do I have to go via 1.1.3 first?
- Do I just do option+restore in itunes?
- Do I need to put the iPhone in restore more first?

2) I am going to use iNdependence to do this, which if I have read correctly, uses Gunlock to unlock the phone. Now have I got this correct; gunlock is just a software unlock. It just patches the baseband and doesn't touch the seczone so I don't need to worry about backing things like that up?

3) Also can Gunlock be removed easily?

4) Do I need to do anything special when upgrading to a new firmware in the future with regards to Gunlock?

5) Are there any problems running the new firmware with the older baseband?
- I ask as I found this today:

That's for apple to know. Reception and battery life are a couple of things that have been noticed. They are upgraded for a reason. The system runs better when the baseband matches the software. Check the logs - they are full of kernel errorswhen mismatching software/basebands. It is your choice tho.

I do also realize I could downgrade the bootloader to 3.9 and unlock the newer basebands with ziphone but I do not wish to do this.

Thanks for any help.

Can anyone help?
