Orange San Francisco SMS problems.........

[Guest fi_pinkangel]

I am having probelms with my san francisco phone, when i try to send a text through messages and input the contact from the phones memory it fails. If i go to the contacts section then select a contact then select send SMS it sends ok. Why doesn't it work when i go to messages and try to input the contact from the phones memory?

I have unlocked the phone and am using a giffgaff sim card but have made no other alterations.

I am using Android 2.1.
