If you want to use custom message on your iphone screen with Server Lock Example, here is how you do it. (My phone is 3G, firmware 2.2.1)
First download a Terminal app, then download vim (or any text editor). Assuming you have Winterboard and have Server Lock Example turned on, we are now ready to go!
Run Terminal, then cd /Library/Themes/Server Lock Example.theme/
Run " ls -l", you will see that there is a file called LockBackground.html. However it is owned by “root”, and you are “mobile”. So, let’s su as root then. The password is “alpine”.
Run " vim LockBackground.html".
Here due to the limited keyboard, the arrows keys are gone along with other important keys such as the ESC key. Luckily I found ways around it. You will see this file:
You can see that the message “This doesn’t really do anything yet, but it /did/ get loaded off the server ;P. (Awesome, huh?)” is from http://cydia.saurik.com/lock/. Well, what do you think? Change that link! ;)
Let’s just say you want to change that link to http://www.myWebsite.com/lock/, because this link will display something cool! (Or you can display some contact info in case you misplace your phone).
To move down, press " return". When you get to that line, press space to move right. When you are on the letter “c”, press " x" to delete until you have “http://.com/lock”. Now press " i" to go into insert mode. Then type carefully “www.myWebsite”.
After that, you need to quit the insert mode. Poor me I couldn’t find the ESC key. But if you use your finger to press the terminal, a little keybad thing will show up. These are supposed to be command line shortcuts like grep, find, etc. I went to “find” and the find command typed out for me. So now for some reasons you are out of the insert mode, but with a find command. So, just " x" them until you have your “http://www.myWebsite.com/lock/", see below.
If you make too many typo, then trigger the find command, then type " :q!” to quit vim so that you can start over. Yeah, start over… ^^;
Once you are done, type " :wq" to save.
So there you have it. A custom message from your own server!
