iPhone

The first requirement is that you have a jailbroken iPhone.
Through the app Cydia one has to download the app OpenSSH.
After downloading the required software you have to establish a connection between your computer and your iPhone so you can open the ssh connection.
In this solution both are members of a secure WLAN. (iPhone IP in this example: 192.168.1.2)
The standard login credentials for the ssh-access are usename 'root' and password 'alpine'.
The SMS archive is stored as '/var/root/Library/SMS/sms.db'.
If you just want to copy the database you can use this one-liner:
>scp root@192.168.1.2:/var/root/Library/SMS/sms.db /home/user/
After entering the password the transfer should start.
If you want to browse the filesystem you can do this by connecting with ssh:
>ssh root@192.168.1.2
After entering the password you should be able to access the filesystem.

If you have an application to view sqlite3 databases you can start browsing the archive.
Example:
>sqlite3 SMS.db
>.tables (shows the tables in the database)
>.schema message (shows the schema with all the triggers of the table message)
>SELECT * FROM message ORDER BY `date` DESC; (lists all saved messages ordered by the date in descending order)

 To secure your SSH connection the password for "root" has to be modified. Please, regularly change this password. Start the Terminal of your Mac or Shell of your Linux computer. For Windows an SSH application such as Putty is necessary.    

1. Then type the following line of code, but before replace the palceholder "ip.des.iph.one" with the IP address of your iPhone to create the initial SSH connection: ssh root@(ip.des.iph.one)
2. The standard password for all iPhones is "alpine". Type password and confirm with Enter (Please note that several Unix systems handle backspaces as new input characters).
3. To change the root password, type "passwd" now.
4. Then the new password is requested: Type in the new password
5. Retype the password to confirm it
6. Disconnect from SSH by using "Exit" (Or stay connected, if you need the SSH connection for other tasks

(Note: For iPhone without installed SSH Server this series of steps is impossible and not necessary)  There is a legal issue that hampers the overall SSH usage: Only applications from the Apple "app store" are legal to be used on an iPhone. The SSH solution is often referred to illegal "Jailbreak" solutions which cannot be recommend from legal perspective ;)However, this issue should not be ignored for all iPhones using such SSH solutions.
