I've got a jailbroken apple iphone 4 running the new ios 4.3.3 where I wish to run Apache, MySQL, and PHP. All the information I have found is hopelessly outdated.

Exist packages I'm able to install through Cydia or apt-get with this?

Any prodding within the right direction is a lot appreciated!

It appears you will find individuals who attempted this - http://www.ipadforums.net/ipad-hacking/24007-running-php-server-ipad.html and http://claytond.com/2007/11/07/an-iphone-powered-apache-web-server-with-php/

However I aren't seeing mysql, also read comments some reported that preg_match wasn't working. Might be handy, however, you gotta run all of your tests before releasing the energy :)
