Regarding the vCard 2.1  
"specification":http://www.imc.org/pdi/vcard-21.rtf I did some  
researches once again.

It is described in Section 2, that property names and property  
parameters can be defined as case insensitive:

<pre>
A property is the definition of an individual attribute describing the vCard.
A property takes the following form:
PropertyName [?;? PropertyParameters] ?:? PropertyValue
as shown in the following example:
TEL;HOME:+1-919-555-1234
A property takes the form of one or more lines of text. The specification of
property names and property parameters is case insensitive.
The property name can be one of a set of pre-defined strings.
</pre>

This fact is consistent with  
"RFC2426":http://www.ietf.org/rfc/rfc2426.txt (page 29 and 31). So a  
"vCard reader module" is meant to support both spellings.
