will the newer update of itunes ruin 4.3.3 JB devices?


I am new to this so bare with me, what i did not understand is if iTunes updates can ruin JB 4.3.3 ipads some how, the reason im skeptical about it is that i read on some sites that other JB 4.3.5 methods exists but not for 3g iPad 2s, so is this the case?

You may not be able to install custom FWs with a newer version in the future but all versions out now are compatible and won't cause any problems.
