Mobile phone ICE security

I’ve started a thread about this over in the “General” forum to gather some responses to help others in this group, but the basic issue is this: on my new cellphone (LG Env2), the text fields in the ICE (In Case of Emergency) area are completely editable and eraseable even when the phone is locked. (The actual contact numbers are still read-only/read-and-phone-only.)

Has anyone else here run into ICE information security issues on his or her mobile devices?
