Can anyone help with this? i have an iPhone and an edifier speaker (Clock) similar to the
apple iPod Hi-Fi.

In both units (edifier and Hi-Fi) when i connect the iPhone it says that the accessory was not built for iphone and if i want to go to airplane mode...They work great!

Two questions:

1- Will the Edifier and Hi-Fi damage the iPhone? Why? is it because different voltage?
2- How i stop that annoying alert on iPhone every time i connect it?
