Give me some advice about my new iphone

@op have you tried itunes yet? i believe apples uses that app for any and all of their portable devices.

I think Currently this is only available in email form. Just click the little envelope at the bottom of the notes page and email it. Hopefully there will be a way to sync notes soon. If Apple doesn't do it, there could be an app after the sdk is released.
If it still don't work ,you can refer to the page about how to transfer iPhone contents to Macbooks.
Hope it will help you..

you can sync with itunes. or you can upgrade to easily synchronize ios5. or you sync with a software application other from cydia
