Hi all, I got a bit tired of android and I thought now it was a perfect time for me to get an iPhone for the first time. I currently have an S3 but my new iphone 5 will come in two days. What kind of changes should I expect?? What should I do first when getting my iPhone?? i am nervous and exciting as hell. I also own a macbook pro. How can I use both together to my advantage? thanks, I will be new to this.
