I think you may need to hard reset, once it boots for the first time it should run the customisations which are stored on the Extended ROM (which is usually hidden). The alternative is to un-hide the extended ROM and run the file manually. I'm going to try and unhide my extended ROM so I can install Opera Mobile, which also isn't on mine as I did the soft reset before allowing the customisations to run.
I'll post details of what I did once I've done it!
