I dont think that they have developed a new wallet in just a day, because i was trying to look for a wallet to store some iota yesterday, but there wasn't any.
they haven't released any wallet yet, if you want to buy iota, you just need to store them on bitfinex or binance, that is the only way that you can hold iota at the moment.
They are going to add it to the Ledger App in a few weeks, so stay stunned because that is one of the best ways to store coins.
Okay sounds good ill keep a lookout for that. I looked into the github one and apparently there is one but the password has to be 80 characters long and you constantly have to update the wallet...
