Just figured I'd share with the class:
I've had a Trezor 7 since they've come out - but I've been disappointed by the lack of Monero support both on the Trezor app and the official Monero-gui wallet.
That is, until today. A very small (relatively unknown app) called Monero One has native Trezor support via bluetooth - and it works great!
I'd suggest you check it out if you have an iPhone. I personally prefer it over the Cake Wallet.
