So i download the bitcoin.org wallet on my iphone
There is no "bitcoin.org" wallet.
This site lists a few wallets for you to choose. It would be good to know which wallet you have downloaded.
[...] i do have the seed to recover it.
That's good!
This means that you can download any BIP39 compatible wallet (e.g.
electrum) and insert your mnemonic code there.
Make sure to choose the correct derivation type, depending on the addresses your old wallet had:
- "P2PKH" to restore addresses starting with 1..
- "P2WPKH-P2SH" to restore addresses starting with 3..
- "P2WPKH" to restore addresses starting with bc1..
Im on a windows laptop now and downloaded the bitcoin.org wallet app but it just created a new wallet.
There also is no "bitcoin.org wallet" for a desktop system.
Did you download bitcoin core? Because that wallet is not BIP39 compatible and you therefore can't restore your wallet using a mnemonic code.
