You'd probably want to use FTP or HTTP to download the update image, if the modem can't stage the file, you'd probably want to have some memory to stage it.

If you're not familiar with the IAP (In App Programming) methods/examples you'll probably want to start by reviewing and understanding those.

Thank you. I will have a look at IAP. wasn't aware of that before.
