Dell Streak 5. Contacts display problem

[Guest anotherbob]

I have synced my Streak (unlocked and on 2.2) with my Google account and all my contacts appeared OK. Then I put my sim card in which has another set of contacts from a previous phone. Now my Streak shows all contacts (Google Acct. + Sim) and my contacts list has twice as many as I need.

I can't find any way to tell the Streak to ignore the contacts on the Sim, and there is no way to delete them either, (except one at a time!!!). I want the Streak to list contacts from my Google account only. How can this be done?
