Hi guys,
I am new to this forum, I have an otb 1.1.2 which has been downgraded to 1.0.2 and its working perfectly with turbo sim (already programmed with my carrier sim).

If I want to upgrade to 1.1.2 via 1.1.1 and oktoprep do I need to install any software on Iphone once its back to 1.1.2 to use it with turbo sim or do I just insert the already programmed turbo sim with my carrier sim into 1.1.2 and it will be ready to go.

Also, do I keep the turbo sim in iphone when upgrading to 1.1.2.

Thanks so much for your reply in advance.
