The EOS tokens in your wallet at this point are not going to be unfrozen since they are the old ERC20 tokens and their smart contract is no longer active. From this version though, you can disable EOS so that the balance shown doesn't throw you off.
Now as far as supporting the main EOS, I can't say. We don't comment on future development. 🙂
If you want to claim your mainnet EOS now you'd have to use a third party wallet, although we are actively looking into providing a way to claim your EOS from within Exodus and send it to another wallet. But no ETA I'm afraid.
