Of the "big 4" cabs, only Nav and TV can be installed to Internal Storage since the installation path in the cab is %InstallDir%. Opera and Picture Mail use %Windows%, so can't be installed to Internal Storage without doing some surgery to the path names in the cab files.

I'm sure someone will, sooner than later, "fix" the Opera cab so that it can be installed to Internal Storage. (And maybe has already been done - I haven't seen it)
