Spoke to VZ store rep and he agreed the only way (for non-root user) is to delete apps not regularly used. BUT he showed me a trick! First back up apps on Astro (or similar file manager). Then when you delete the app, you can easily re-install when needed from Astro versus having to go back to search Market. I'm now up to mid-40s mb! He also said that personal pictures as wallpaper uses internal memory storage (and emails with large attachments, undeleted messages, etc.). I think with proper "phone management" I can keep the phone running pretty quick!
