SDK 4.3 + xCode 4.0.2 = What to do?

Hi all,

I just finished my game, which is running very well on my device, everything was ok, until i tried to make it ready for distribution.

First of all, the apple user guide 2.7 images don’t match at ALL the my xCode version, so it was even at the beginning a pain in the ass to even try to set up the project.
Then after i lost all my hair trying to understand or find the good button which were not at the same place, i heard about this thing:

SDK 4.3 crashes, and its better to use xCode 3.2.5 AND 4.2

So the question to the community and especially to the dev team is that:
i bought MBP only for my project, so, how the new comers can know about that issue ?
How do i do to downgrade now ?
What should i do ?

Paradoks

Ok, AngryAnt told me that you just have to rename the Developper’s folder, and install the old xCode and SDK:
https://developer.apple.com/devcenter/download.action?path=/ios/iossdk_4.2__final/xcode_3.2.5_and_ios_sdk_4.2final.dmg

lets try …

search forums - there was a thread about it with Mantas posting what to tweak to avoid crashes when using sdk4.3
