Hi,

What do you mean by "hide"?
Do you want to hind the SMS details of a particular contact within the
Contacts application, or are you wanting the device to receive and process
SMSes from a specific number without giving the user any notification or
alert?
If you want to perform the later, you should investigate developing an SMS
message interceptor. This would allow you to intercept any SMSes received by
the device from a particular number, and do what ever you want with them,
without them reaching the SMS inbox, or alerting the user.
Hope this helps,
