Downgrading from 4.3.3 keeping baseband?

[EpicKN]

Right now I am on 4.3.3, baseband 1.59.00

Friday I am going to get my iPhone checked at the apple store because the top power button is stuck and only works 10% of the time, requiring a ton of pressure.

So I figure I should unjailbreak it before I give it to them. If they give me a new one, this will all be for naught, but in the chance they want to charge me for a new one, I'll just keep the one I have and re-jailbreak it.

I want to keep the baseband in tact though, just in case.

Can I get some links to forum topics that can help or just someone walk me through the steps?

Thanks!

To unjailbreak, You need to restore to stock 4.3.3 using tss server and fix recovery 43 to exit error 1013 .

This will maintain your bb.
