We make sure that our cases will be compatible with at least the official cable that come with the phone.
With other third party cables however, it might not be 100% compatible as there are quite a few on the market.
Considering the importance of a case for your phone, we believe it is easier to buy a cable fitting your case rather than buying a case that fit your cable. Having said that, please be aware that we do our best to make the port as big as possible, while still providing sufficient protection.
For docks, the PlayProof and SolidSuit will be usable with the Apple Dock. The CrashGuard however will not.
If you want to know the dimensions of a case's port opening, you can write to us via email@example.com.
