Are speakers in the store that are available for the Ipad Air 2 Wifi version compatible with the cellular version as well? Common sense says they would be but I wanted to check to make sure before I tore down my iPad
The speakers should be the same, as there is no reason why Apple should make different models of the speakers for the cell and wifi iPads. If you can, compare pictures/serial numbers and see if you spot any differences, but I can say for sure that they shouldn’t be any different.
