How to Merge All The Sections In Garageband?

I have Garageband on my iPhone 4S, and I have created two separate "sections". When I try to play both sections it just plays the first one repeatedly.

Someone help?

How are at&t and Verizon iPhone different?

I was trying to order a new Iphone backplate. I don't understand why one backplate would fit on one carriers iphone versus another even though the hardware themselves are exactly the same and from the same company?

Added (1). That's the thing, i would only be replacing the back-plate.nothing around the volume buttons.

Added (2). Okay that's interesting and all… However that still has nothing to do with the actual physical hardware. And I happened to have known that already anyways. Now that I've looked that up i'll share with you how GSM and CDMA differ. "What's the core difference? It all has to do with the way your data is converted into the radio waves that your cellphone broadcasts and receives." That was from a random website off of google.So, is there anyone that can give me an actual reason as to why the back plate, or back glass, would fit on networks iPhone 4 versus another networks iPhone 4?

Added (3). Sorry
would only fit on one of the networks iPhone 4, and not the other networks iPhone4?**
