I was using Phonegap with XCode 3 but when I try Phonegap(phonegap.0.9.5.1) on Xcode 4, my project compiles but does not work as expected just after installation. ERROR: Start Page at 'www/index.html' was not found. message comes up. You have to copy "www" directory and "index.html" by yourself into your project, should new versions always cause problem? Anyways, here is a detailed explanation; http://wiki.phonegap.com/w/page/39991939/Getting-Started-with-PhoneGap-iOS-using-Xcode-4-%28Template-Version%29

If you are getting Access Denied error while trying to download new XCode, it means you need to accept the license agreement.(yes I do agree, why does not Apple just put a link to that page as "click here to see the agreement" rather than just saying Access Denied?) Anyways, here is how you can read and sign the new agreement; 1. Go to "Member Center" on top right corner. 2. You will see a yellow line which says there is a new agreement you need to sign to access developer resources.(why does not this show up when I login? I do not know!?) 3. Read and sign new agreement. You are done, go to Dev Centers->iOS. Click on Downloads and "Download XCode 4". Happy coding...
