are nanowallet and mobile wallets use same way of backup import keys?
means can i use same addresses on both?
You can use the same private key in Nano, Android, Lighwallet, and NCC and you will have the same account on each wallet.
Also, NCC has an option to export wallet to Lightwallet format. That wallet will work in both Nano and Lightwallet. And now that the Android app is out, the next update to Nano in a week or so will also have an "export wallet to Android" option where the app just scans a QR in Nano and now you have the same account on your phone and your desktop.
Can we add a second account to an existing nano or mobile wallet using the private key? Or do we need to import a second account into a second wallet?
