There is no way to bring over the text from your old iPhone. Unless maybe you were using a texting app, and not iMessage. Not sure on that though.
The big key when setting this phone up from iphone, was to turn off iMessage before you ever activated this phone. I had actually shut down iMessage and continued to text a few friends, until I got home and on wifi to set the new phone up. I haven't had any issues with getting my texts.
I almost wonder if reactivating your iphone, send a few imessage texts, and then shut off imessage, and text some more, and then shut everything down, and reactivate the Note. Not sure if that would help, and I know if seems like a lot, but could possible fix it, as it would be a cleaner switch between services.
