const char *attributes = "T@\"DeliveryPlatform\",&,D,N";
const char *ret;
char buffer[1 + strlen(attributes)];
strcpy(buffer, attributes);
char *state = buffer, *attribute;
while ((attribute = strsep(&state, ",")) != NULL) {
	if (attribute[0] == 'T') {
        	ret = (const char *)[[NSData dataWithBytes:(attribute + 3) length:strlen(attribute) - 4] bytes];
	}
}
    
NSLog(@"%s", ret);

ret is sometimes terminated and sometimes not, this only happens if the char* we pass in is 16 chars long. Note this only happens on iOS 6 and is not happening on iOS7 anymore, seems that Apple fixed it.
