I've installed the Burger wallet and the 'getblockhash 73805' came up with the correct hash but the wallet says "Wrong Chain, Update Your Wallet" is this OK ?
you mean the skull on the right side?
I'll have to remove this graphic, it's still there from the initial test we did on block >=800.
It has a different meaning on testnet. I'll remove it.
Your testnet version is good, don't worry.
I have to figure out how to best adjust the looks of the testnet wallet... can't keep it like that.
I'll create an updated version.
