I have an idea that may be useful, but I thought I would ask everyones opinion.
Most network carriers charge a set rate for GPRS connections, to send emails and other files, and another set rate for MMS.
For instance, if I sent a file via MMS on my carrier, it would be about 50 cents. If I send it via an email it would be a few dollars. Obviously, the more I send via MMS, the better for my wallet. Unfortunately, you can only send a certain type of file via MMS (picture, audio, video)
It has long been possible to embed .rar files in .jpg files. All you need to do is RAR whatever file you want to hide, and then use the command line to embed it in the JPG file. The command is something like:
Copy /b OriginalImage.Jpg + Filetohide.txt.rar ImageWithHiddenFiles.jpg
So, Windows Mobile can run both Pocket RAR and PocketCMD. I have been testing it and as yet can't manage to get it to work quite correctly, but I believe it is possible (I can create the new image with no rar inside, and can also create a JPG with the rar hidden inside but no image loads).
So, first questions, does anyone thing this is legal considering you would still technically be sending a JPG? I wouldn't want to do any fraudulent or illegal as XDA Developers is a safe site. If it is illegal I won't speak anymore of it.
If people think it is ok, does anyone think it is possible to streamline the process using mortscript?
PS I checked Google and the XDA Search, couldn't find any other related topics, so sorry if this has been discussed before.
