I have searched around and found various options but they all seem to be working for desktop only.
The project I am currently working on needs the libraries to be MIT and/or GPL licensed.
I have found this library named jQuery Image Crop (http://codecanyon.net/item/image-crop/5348464) which does exactly what I need but is not distributed under a MIT/GPL license.
Does anyone have an alternative/suggestion for me ?
Try with jcrop. I'm using it for my project. Works fine in mobiles. Here is the link: http://deepliquid.com/content/Jcrop.html
