You do not have to type extension in your filename. like "iphone.jpg" is not working. just write "iphone" in filename because you already define mimeType. And also you have to define path for resource.

Below is the sample code to attach "rainy.png" file with mail.

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;

[picker setSubject:@"Hello"];


// Set up recipients
NSArray *toRecipients = [NSArray arrayWithObject:@"[e-mail]"]; 
NSArray *ccRecipients = [NSArray arrayWithObjects:@"[e-mail]", @"[e-mail]", nil]; 
NSArray *bccRecipients = [NSArray arrayWithObject:@"[e-mail]"]; 

[picker setToRecipients:toRecipients];
[picker setCcRecipients:ccRecipients];  
[picker setBccRecipients:bccRecipients];

// Attach an image to the email
NSString *path = [[NSBundle mainBundle] pathForResource:@"rainy" ofType:@"png"];
NSData *myData = [NSData dataWithContentsOfFile:path];
[picker addAttachmentData:myData mimeType:@"image/png" fileName:@"rainy"];

// Fill out the email body text
NSString *emailBody = @"It is raining";
[picker setMessageBody:emailBody isHTML:NO];

[self presentModalViewController:picker animated:YES];
[picker release];

This error seems to be related to the running mail int he simulator and not to your code. Even stock Apple's sample MailComposer reports identical error in the simulator:

Add following method to dismiss the MFMailComposeViewController:

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:   (MFailComposeResult)result error:(NSError*)error

 {
 // NEVER REACHES THIS PLACE
 [self dismissModalViewControllerAnimated:YES];

 NSLog (@"mail finished");
 }

use this for attach image in a mail, tested in ios 4,5,6

    MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
    UIImage *myImage = [UIImage imageNamed:@"image.png"];
    NSData *imageData = UIImagePNGRepresentation(myImage);
    [mailer addAttachmentData:imageData mimeType:@"image/png" fileName:@"image"];
