Will The new iTunes version 10.1.2 UNDO my Jailbreak? Help needed Please.

[Kalaharijack]

Hello All,
I really appreciate ALL the advice and help many of you have given me over the past months, Without your assistance I'd be totally lost.

Maybe you can answer this one,
I recently bought Via iTunes --7.0 MPX camera, It worked OK UNTIL apple advised me that I need the NEW version of the iPhone OS, I think this is 10.1.2: OR my 7MPX Camera app will NOT work.

I am NOT sure what version of iTunes OS I have at present on my phone, BUT looking under 'General' 'About' (on my phone) it shows Moderm firmware 05.12.01 and 'Version' 3.13 (7E18), IF that helps.

IF I install this new OS, Will it undo my Jailbreak?
IF it does not then I'll install it, BUT I have read that it is not a very good OS, Can anyone of you clever people assist me?

Your comments and advice would be most welcome.
Regards and Respect

Updating iTunes does not undo your jailbreak. Only installing a newer firmware or restoring your device will undo your jailbreak.
