I tried to search for it, but I didn't find any threads that dealt with this problem.
Is there a way to 'batch install' .sis files or themes onto the phone? Now, when I upgrade the firmware, I have to install every application and theme by hand -- one by one, using the PC Suite (or having them saved in the memory card and installing from there). This gets to be a chore because I have two phones and many themes and apps 😞
Is there some way to have a list of applications (sis files or theme files) and have the phone install them all without user interaction?
Nope. A .sis file can include other .sis files, but you'll never get the installation work without user interaction (if the system allowed that, it'd open up a way for malicious app to get installed without user interaction, too).

Normally if you update your firmware and then start your phone.;if your memory card is inside it should automatically reinstall the apps 'on it' back to where they should be.
Assuming the app has been well written by the original developer in this respect. Some (many) apps do not behave like this, unfortunately.
