The accepted answer is wrong . Creating a new target is how you create a separate iPad app from an iPhone app (ie a project that can be compiled into either an iPad or iPhone app), it is not how you convert an iPhone app to a single universal app that will run on iPhone or iPad.
All you actually need to do is switch the Device dropdown in the target summary tab from iPhone to Universal:
