provisioning profile problem?

i am running my apps with different provisioning profiles.(I am creating one provisioning profile for each application an running in device). but i want to run all applications in my device(without overwritting previous apps) with only one provisioning profile.I hope , it is possible.when we set apple id only in plist file as "com.myappleid.identifer(开发者_开发技巧123145^&)" identifier will come uniquely automatically.can any one give simple tutorial to create the provisioning profile? can i use my previous development certificate for that provisioning profile?

I think you want a wildcard provisioning profile. If all your apps start with the same identifier, e.g. com.myappleid.App1, com.myappleid.App2... then you can create a provisioning profile with the identifier com.myappleid.* which would match all of the above.
