How to get guiComander file off iPad?

[Jon Ross]

I've recently purchased a used boat that is using iViewer4 on a iPad to control an e-plex system. Via a iPlex interface and a iTach TCP<->Serial node.

I need to change the network/DHCP settings on the network (don't ask), but it seems like the iViewer4 has the IP address of the iTach server hard-coded in its gui file (AFAICT).

How can I get and modify this file? All the companies involved in the installation and configuration of the boat, including the boat manufactures, are all defunct. So I can't ask any of them. I assume it's on the iPad someplace? Can I just pull it off somehow?

Secondly, can I modify it w/o needing a license?

Thanks,
