certificates, provisioning, ...

Basically you can/will find a very detailed description at Apple but at the same time also a very confusing description. Apperently you have to do the right steps at the right time. But still, you need to read Apples and Unity How-To at:

Components/Unity%20iPhone%20Basics.html

Start:
You have to be a member in the Apple Developer Program. So get an account first and login. Go to “Program Portal”. Go to menu App ID. Create App ID with Wild Card Asterisk and reverse domain name. Read through Apples How-To to understand.

Step 1:
Download and install AppleWWDRCA. After downloading double-click it. Keychain Access will open, click OK. (Keychain Access is a pre-installed application on your Mac; german: Schlüsselverwaltung)

http://developer.apple.com/certificationauthority/AppleWWDRCA.cer

Step 2:
Create locally on your computer two “Certificate Signing Requests”! One for development and one for distribution. Make sure nothing is selected in main window of Keychain Access. Go to Keychain Access -> Certificate Assistant -> “Request a Certificate From of a Certificate Authority…” . (Also check flag below “save to file” radio button). Save(!) requests with individual names on your computer.

Step 3:
In your Developer account go to “Program Portal” (http://developer.apple.com/iphone/manage/certificates/team/index.action)

Step 4:
In “Program Portal go to “certificates” -> open tab “Development” -> request certificate -> load developer-certificate-signing-request that you created in Step 2 -> Approve it! Refresh page after several seconds: you should see a download button. Download certificate (developer_identity). After downloading double-click it. Keychain Access will open, click OK.

Step 5:
In “Program Portal go to “certificates” -> open tab “Distribution” -> request certificate -> load distribution-certificate-signing-request that you created in Step 2 -> Approve it! Refresh page after several seconds: you should see a download button. Download certificate (distribution_identity). After downloading double-click it. Keychain Access will open, click OK.

Step 6:
In “Program Portal” go to “provisioning” -> open tab “Development” -> click/create “New Profile” ->Submit and approve it! Refresh page after several seconds: you should see a download button. Download provisioning file (name it for example Development.mobileprovision). After downloading drag file onto Xcode or iTunes icon in your Dock to install. Alternatively open Xcode -> window -> organizer -> provisioning -> click on “+” button and load development provisioning file. Detailed description in Apples How-To if necessary.

Step 7:
In “Program Portal” go to “provisioning” -> open tab “Distribution” -> click/create “New Profile” ->Submit and approve it! Refresh page after several seconds: you should see a download button. Download provisioning file (name it for example Distribution.mobileprovision). After downloading drag file onto Xcode or iTunes icon in your Dock to install. Alternatively open Xcode -> window -> organizer -> provisioning -> click on “+” button and load distribution provisioning file. Detailed description in Apples How-To if necessary.

Prepare UnityRemote project or other Xcode projects for building.
