I heard people talking about Smart Messaging FAQ & Specs, but when i read those two documents, they make little sense to me. I only see how to encode this and that, and none on how to send Operator Logo or Ringtone thru Nokia SDK.

Can someone please brighten me?

Two more question below.
1) Oh by the way, what is Little-Endian BCD ?
2) After you encode an operator logo or ringtone, how do you use the encoded data?
3) I also see syntax like "<operator-logo> ::= <operator-logo-header> <ota-bitmap>", how do one use this info?
