Transfer Data without overwrite

[insite]

I have an IPhone 3G which is on its last legs. I also have an IPhone 5.

Both have separate data and are individually backed up on I Tunes.

What I would like to do is to transfer all the data and apps from the 3G to the 5 without loosing all the information on the 5.

At the moment I do not use I Cloud and am not sure if the 3G has this facility

Can this be done and if so how ?

Thank you for any help.

in this situation the best you can do is keep them as two separate gadgets and just sync content to them

dont restore from the 3g backup or it will overwrite your 5

all you can do is keep the existing stuff on the 5 , but keep syncing the same content, like music, tv shows, movies, photos, videos, books and apps

if there are any settings you want to restore from the iPhone 3g, don't do it because it will overwrite everything

but syncing should be fine
