I recently bought a Samsung NoteII for my birthday. It was an upgrade from my iPhone 4, but i deeply miss the iMessage feature. I still have my iPhone 4 and am going to return the NoteII. But with recent buzz about an iPhone5S coming this April-June, I don't know what to do. I have two options ; 1) Keep my current iPhone 4 and wait for a new model. 2) Get rid of my iPhone 4 and get the iPhone 5. As of now, my iPhone 4 works fine and gets the job done. And i truly don't see that big of an improvement from the 4 to the 5. But what should i do?
