please help.. thanks in advance.
For some of this, it depends on how you saved it...
With media (pics, movies, and other files), you can either just switch the SDcard to the new phone, or if you're using internal memory, you'll have to connect the old phone to a computer, back up the contents, then transfer them to the new phone.
Apps should re-install themselves automatically from the play store.
Regarding messages and data, some of that can't be backed up unless the phone is rooted. It's been a long time since I've had to do it, but at the very least you'll probably need to run a backup app on the old phone, and then restore it to the new phone. I'm sure others can be more specific with this one. (EDIT: See above about "My Backup")
