Use this code https://gist.github.com/1064652 for fix image orientation before uploading it to the server.

UPD:
Click to create new file, select Cocoa Touch, then Objective-C category. Then write FixOrientation in “Category” field, and UIImage in “Category on” field. Then click next and complete files creation.
After that, insert method declaration

- (UIImage *)fixOrientation;

in UIImage+FixOrientation.h

and copy implementation from github to UIImage+FixOrientation.m file.

Next, add

#import "UIImage+FixOrientation.h"

to your class, were you work with image.

After that, replace string

NSData *imageData = UIImageJPEGRepresentation(image.image, 0.09);

to string:

NSData *imageData = UIImageJPEGRepresentation([image.image fixOrientation], 0.09);
