Hi, I've lost option to save contact to sim

[atmop]

Hi all, up to now when saving a contact I had three options: Phone, Sim and Gmail. But now suddenly the Sim option is gone and I can only save to Phone or Gmail contacts. I did delete a few apps yesterday but cannot figure how this has happened. I cannot figure it out as 'sync to gmail' is OFF under 'accounts and sync' in settings. (Pnone: Samsung i5500 Android 2.0)
please help
Thanks
Vincent
