Is there a way to backup my iPhone text messages without Jailbreaking it that is Windows-compatible also?

I'm looking for an easy-to-use Windows program that will allow me to backup and save all of the text messages store from my iPhone onto my computer. I know Syphone is one such program, but it's for Macs only. Please help!

I am using Tansee iPhone Transfer SMS. You can easily find it at:

First of all, it is for windows users.

It can perfectly backup SMS in iPhone to computer. You can transfer the messages to computer as a txt file or a ANTS file as you wish (I personally choose to transfer as ANTS file for that allows me to protect the file with a password to keep all private).

Moreover, you can View and Manage old iPhone SMS in your computer.

Before the transfer, you can choose to transfer messages from all contacts or from a single contact.

Here is the detailed guide showing you how to operate:
