Help Fix Bug With HTML5 ImageUpload Using iPhone 5

Hi, we are having a strange issue with our image upload functionality which uses html5 and is working great with ipad, iphone 4, android and pc browsers. It even works with an iphone 5 simulator! But with actual iphone 5 it is not working in both IOS or in Chrome which leads me to believe there is some difference in way iphone 5 encodes an image? I'm guessing that's why I'm looking for an expert in IOS, HTML5 and java. I believe uploading part is OK, but the processing of the photo is hanging. Please bid for 3hrs of work and if need more time I can add bonus or create another project thanks.
