(I had some troubles receiving it, and I had to reorder it, too based on changes in the shipping dates).
they had to divert it through the NSA backchannel, nothing to worry about Jay

I am not ruling that out completely - yet back to the original question, anyone split their BCH after reseeding the ledger nano s?
Here is the official word from Ledger (latest I know of anyhow):
https://blog.ledger.co/managing-the-bitcoin-cash-fork-7229dde3f358Roughly speaking though, the "Bitcoin" Chrome App offers access to 3 wallets: Bitcoin, Bitcoin Cash and Bitcoin Cash "Split". The later being in a different part of the HD hierarchy to improve safety. The first two using the same addresses but on different chains. If you're super paranoid about possible future replay attacks, move your bitcoin first. I'd suggest moving your BCH into addresses into the "Split" wallet so that you are convinced you have the balances and control over the coins. Then keep them there or do whatever you wish. There is no "tool" or software for doing this per se from Ledger. Just the wallets and control over the addresses provided.
PS haven't tried reseeding from a bitcoin.info wallet, but would assume it would work like any other reseeding with a BIP39 seed, unless they do something special.
Thanks for the responses and the blog link, els.
I had seen that linked blog article before, but it is making more sense now that I have the ledger nano s in my grubby little hands.
I remain a bit nervous about all of this, and I am looking into each of the various matters, now, and I had seen some other reseeding explanations on the blockchain.info subject that I will read through again too. There were some on blockchain.info and I had seen some other explanations, too, but I suppose the blockchain.info explanations should be sufficiently clear, even for technical (and nervous) novices like myself.
At some point soon, I will probably post a detailed outline of what I did, once I finish doing it or I might post some more questions if I run into some stumbling blocks while I am going through this process.
I have some other things that I am trying to do, too (and some errands that I have to run later in the day), so sometimes, I get interrupted while I am in the process of preparing to perform this whole splitting thingie-ma-jiggie - but I am not going to rush what I am doing because I certainly don't want to lose any coins, even if the loss were to be only the currently .08 BCHs... hahahaha... even .08-ish can add up to quite a bit of real value.
i suggest you just initialize your nano with the seed and then play around with the bitcoin app and nano to see if you see the expected balances on both blockchains. [it is relatively
to initialize with a seed then zap the nano (e.g. enter 3 bad PIN codes) and start over, so long as you don't sign any transactions along the way.] if you see your balances, then your are almost certainly good to proceed, as the nano has your private keys (same ones for BTC and BCH, until you split them)
