Just for your information, I use claws mail so I've experimented with importing a Google Calendar.
It works but I'm afraid it won't give you what you are looking for - the print out it offers is an event list view and not a calendar view.
Re my suggestion about using a Google Document Spreadsheet - I meant that you would have to migrate to using a Spreadsheet Calendar instead of using Google Calendar - Google has fixed it so that it isn't easy to import a Calendar into a Spreadsheet
My next, and probably last rubbish suggestion, is - Does your cellphone provider offer you a webmail based service other than GMail? There's a small possibility that if it does there may be a calendar application/add-on available in the webmail service.
