Xcode , iphone versions

Question

I am new on iphone I want just change something little to a project. I have A mac os 10.6 , xcode3.2.6 and an iphone 4.3.5 I import the project and it runs ok. When i try to add the app on device I have 2 problems : 1. Xcode cannot find the software image to install this version 2. No code signature found

I can run the app on iphone if I don t update xcode? If I update xcode can I import my project even if it was done in a previous version?

Thank you ,

In order to run the app on a device the code must be signed with a valid developer certificate.

Yes, if you update XCode you can still open projects that were created with previous versions of XCode.
