The Apple app store has a limitation that any apps over 100 mb must be downloaded over a wifi connection, and not a cellular connection. All well and good, but for PCI compliance reasons, I have locked down my devices that take card payments to the cellular network only (whitelisted a wifi SSID that does not exist).
Any ideas how I can get updates for apps over 100 mb (e.g. Square POS) with this restriction in place, or a way to schedule removal of the whitelist, force the update, and then reapply the whitelist?
Why not create a wireless network that the devices recognise and turn it on when you need to update app and back off once you have finsihed. Otherwise you can make an ethernet adaptor as shown in the below thread but this requires the devices being bought to you for update.
