Upgrading Xcode to 3.2.3 SDK iOS 4 issues: my solutions

Ok, I upgraded my Xcode with this new version (3.2.3) and new iPhone iOS 4 SDK.
Unfortunately, the upgrade was almost painless...ALMOST. 

Issue #1: 
base sdk missing

Solution:
Project -> Edit Project Settings. 
Then in the tab called "Build" find Architectures. 
Set "Architectures" to Optimized and "Base SDK" to iPhone Simulator to 4.0 or 3.2 (ipad).
You'll need to do this for every project you have.

Issue #2:
HTTPriot (http://labratrevenge.com/httpriot/docs/) stop working (32 errors)

Solution:
Download sourcefile and compile yourself the example project.
After that, you should replace the file libhttpriot.a in the right directory (in my case it was iphonesimulator3.2.sdk/usr/local/lib/)

Issue #3:
ld: library not found for -lcrt1.10.6.o

Solution:
Project -> Edit Project Settings.
Then in the tab called "Build" find Deployment. 
Change "Mac OS X Deployment Target" from 10.6 to 10.5.

I hope this may help you!
