Apart from choosing your client or programming interface, usage does not differ from any other string field.

[Update] I haven't had the luck to develop for the iPhone yet, but I believe it's the same as any other SELECT or INSERT query. Make sure to encode the BLOB and enclose it with single apostrophes (') like strings.
