-snip- and I'd like to find a good Monero Wallet to use with my Hardware Ledger Nano S on my computer as I assume to date it's not possible to send or receive cryptocurrency via a iphone or android device?
If it's about Monero, I doubt people here in Electrum board would be willing to give you answers since it's off-topic.
If you want, you can post a new topic in 'Altcoins' or 'Wallet Software' board regarding that matter.
As for sending or receiving cryptocurrencies in Android or iOS in general, there are a lot of SPV or centralized wallets out there that works in either platform.
