Once you have a development certificate installed, the next step is to specify which devices are to be used to test the ios4 developer you are developing. This is achieved by entering the Unique Device identifier (UDID) for each device into the Provisioning Portal. Note that Apple restricts developers to 100 devices per year.

Installing an iOS Development Certificate in your program
Once a certificate has been requested and approved it must be installed on the development system so that Xcode can access it and use it to sign any applications you develop. The first step in this process is to download the certificate from the iOS Provisioning Portal by clicking on the Download button located on the certificates page outlined in the previous section. Once the file has downloaded, double click on it to load it into the Keychain Access tool. The certificate will then be listed together with a status (hopefully one that reads This certificate is valid).
Your certificate is now installed into your Keychain and you are ready to move on to the next step.

Submitting the iOS Development Certificate Signing Request
Having created the Certificate Signing Request (CSR) the next step is to submit it for approval. This is performed within the iOS Provisioning Portal which is accessed from the Member Center of the Apple developer web site. Under Developer Program Resources on the main member center home page select iOS Provisioning Portal. Within the portal, select the Certificates link located in the left hand panel.Click on the Request a Certificate button, scroll down to the bottom of the text under the heading Create an iOS Development Certificate and click on the Choose File button. In the resulting file selection panel, navigate to the certificate signing request file created in the previous section and click on Choose. Once your file selection is displayed next to the Choose File button, click on the Submit button located in the bottom right hand corner of the web page.
At this point you will be returned to the main Certificates page where your certificate will be listed as Pending Approval:
If you are not the Team Administrator, you will need to wait until that person approves your request. If, on the other hand, you are the administrator for the iOS Developer Program membership or have administrative privileges, you may approve your own certificate request by clicking on the Approve button located in the Action column of the Your Certificate table. Your certificate is now active and the table will refresh to include a button to Download the certificate.

Creating an ios developement certificate Sighing request
Any apps that are to be installed on a physical iPad device must first be signed using an iOS Development Certificate. In order to generate a certificate the first step is to generate a Certificate Signing Request (CSR). Begin this process by opening the Keychain Access tool on your Mac system. This tool can be found in the Applications -> Utilities folder. Once launched, the Keychain Access main window will appear as follows:
Within the Keychain Access utility, perform the following steps:
1. Select the Keychain Access -> Preferences menu and select Certificates in the resulting dialog.
2. Within the Preferences dialog make sure that the online Certificate Status Protocol (OCPS) and Certificate Revocation List (CRL) settings are both set to Off, then close the dialog.
3. Select the Keychain Access -> Certificate Assistant -> Request a Certificate from a Certificate Authority… menu option and enter your email and name exactly as registered with the iOS Developer Program. Leave the CA Email Address field blank and select the Saved to Disk and Let me specify key pair information options .
4. Clicking the Continue button will prompt for a file and location into which the CSR is to be saved. Either accept the default settings, or enter alternative information as desired at which point the Key Pair Information.
5. Verify that the 2048 bits key size and RSA algorithm are selected before clicking on the Continue button. The certificate request will be created in the file previously specified and the Conclusion screen displayed.

note:do not Click Done to dismiss the Certificate Assistant window.
Joining the ios developer Programe
Being a member of the iOS Developer Program should not be confused with being a registered Apple developer. Being a registered Apple developer only gives you the ability to download the iOS SDK and access to additional developer related information. Membership of the iOS Developer Program, however, allows you to set up certificates and provisioning profiles to test applications on physical iOS based devices and, ultimately, submit completed apps for possible acceptance into the Apple.
Enrollment into this program currently costs $99 per year. It is also possible that your employer already has membership, in which case contact the program administrator in your company and ask them to send you an invitation to join. Once they have done this Apple will send you an email entitled You Have Been Invited to Join an Apple Developer Program containing a link to activate your membership. If you or your company is not already a program member, you can enroll online at: Having completed the enrollment process, navigate to http://developer.apple.com and click on the Member Center link located near the top right hand corner of the screen. On the resulting page enter the Apple ID and password associated with your iOS Developer Program membership to access the member center home pageiPhone,ios4,iPad Biginer guide
Simple apps for iPhone:
we were able to see an iPad application that we had created running in the iOS iPad Simulator environment bundled with the iOS 4 SDK. Whilst this is fine for most cases, in practice there are a number of areas that cannot be comprehensively tested in the simulator. For example, no matter how hard you shake your computer (not something we actually recommend) or where in the world you move it to, neither the accelerometer nor GPS features will provide real world results within the simulator (though the simulator does have the option to perform a basic virtual shake gesture). If we really want to thoroughly test an iPad application in the real world, therefore, then we need to install the app onto a physical iPad device.
In order to achieve this there are a number of steps that must be performed. These include signing up to the iOS developer program.
generating and installing a developer certificate, creating an App ID and provisioning profile for your application, and registering the devices onto which you wish to directly install your apps for testing purposes
