We really tried to make this possible. Unfortunately Apples restrictive USB policy does not allow BitBox02 users to connect to their iPhones. The new hardware of the Nova was needed to circumvent these USB policies from Apple.

Submitting to the policies of the "Made For iPhone" program would have resulted in potential security and privacy compromises that we were not willing to make. With Bluetooth in the form of Whisper, we have found a secure and private way to make the BitBox02 Nova usable on iPhone without compromising our values.

Using twice encrypted Bluetooth also has the benefit of being able to keep supporting security measures like the Anti-Klepto protocol or authenticity check - something that is much harder to do with other ways to circumvent the USB policies of Apple.
