How to transfer SMS/ text messages to computer for iPhone 5?

I'm looking to transfer some of my SMS text messages from my iPhone 5 to my computer for safe keeping. However none of the previous programs I had are no longer working.

I used I'm too iphone and touch copy but touch copy crashes when I connect my phone and I'm too reads my phone as an iPhone 4 and says I have no text messages available.

My iPhone 5 is also jailbroken if that helps. So can any one point me to a program that I can do this whether for jailbroken iPhone or a regular program.

PS I'm not really looking to pay for a program that is over $5 bucks. One time transfer thing only for about 300 text messages.

Use the USB1! XXX

Simply take a try of Syncios manager, which can transfer or backup your Contacts, Notes, Bookmarks and Messages.
