CkoImap *imap = [[CkoImap alloc] init];

int startSeqNum = 1;

// ------------------------------------------------------------------------
// The FetchSequence method is deprecated:

CkoEmailBundle *bundleObj = [imap FetchSequence: [NSNumber numberWithInt: startSeqNum] numMessages: [NSNumber numberWithInt: count]];
if (imap.LastMethodSuccess == NO) {
    NSLog(@"%@",imap.LastErrorText);
    return;

// ------------------------------------------------------------------------
// Do the equivalent using FetchRange.
// Your application creates a new, empty EmailBundle object which is passed 
// in the last argument and filled upon success.
