Unfortunately no. You can move as many apps as possible to your SD card and that'll help. Removing lesser-used apps or even rooting and trying to find a ROM that uses the least amount of space are also options.
Also, apps like Diskusage let you see exactly what is taking up space.
This was the #1 reason why I was so ready to switch phones, as much as I loved my D1. Apps to SD just doesn't cut it for me. I want all apps to be internal.
I agree with Eddog. I want all my apps internal. I have learned that if I am only going to use an app once a month or so, I do not keep it installed. I simply install it when I need it since it's so easy to do. And it gives me another reason/opportunity to play with my phone!!
I still have not ran into a problem - maybe I am just a minimalist...I have no apps on the SD - and over 100mb's of storage left but I don't keep junk and apps I never use just lying around
