Jigging up the structure of songs is a difficult task, especially when you are used to a particular style and way of writing.
I try to approach each new song in a totally different manner to the rest. One of the songs Im working on right now completely abandons regular 'pop song' strucutre; you can hear a half mixed version here:

A B C B A
This is actually a pretty common structure; especially in classical music. Listening to music outside of the commercial song area can really help you come up with different structures.
You can try variations on the standard structure you gave, e.g having no 2 verses or choruses the same or start the song with the chorus. (She loves you and cant by me love are great examples of that).
Or take more tips from the beatles and dont have a chorus at all! Listen to a hard days night. It sounds like it's just some verses and a repeated bridge to me.
Another technique is to have something like Verse Chorus Verse Chorus Outro, where the 'outro' can often be a complete change in the song (fleet foxes do that a lot - e.g mykonos)
