Who I have the same questioned this topic

I'm planning to upgrade to a smart phone in near future. I don't want to loose my contacts in the process so I've used Backup Assistant to backup my contact files. A friend recently switched to a smart phone and said the files from his old phone were not transferable to the smart phone and he had to manually enter all of his contacts to new phone. Question is, if I've used Backup Assistant, can I load all my contact info to new Smart Phone from there or not, are files compatible between old phone and new phone?

thanks for any input.
