Thanks! I appreciate all the confirmations.

You don't need to be sorry for asking, its great to inform yourself, understand whats going on, and ask if there are questions.

As others already indicated, those backups are redundant and will work both.
As long as the key is in it, and you have the password, it will work.
And every backup will have different looking encrypted private keys, since each backup will use different new password to encrypt them.

Just make sure you back up new keys you add.
Once HD ships, one single backup of your master seed will be sufficient to recreate all keys in all accounts you created based on it, though

As long as the address you want restored is there, and the backup has a corresponding password, you should be fine. The reason the private key looks different is because it's encrypted with a different password. But, as a few here have mentioned, just verify the backup from Backup #1, and if it works, you can toss #2. Verifying will absolutely prove that the backup works fine.

I think that your interpretation is right. Same private key encoded by different password mean different encoded-privatekey.
But lets wait for more confirmations from the others before you discard one of the backups. 

I'm still holding on to both Backup PDFs.  I'm just trying to understand whether the two are redundant because they both point to the same private/public keypairs on the blockchain.  I have not done anything with the keys on my phone's Mycelium wallet, but let me ask my question in another way:  If I were to trash my phone and try to start from scratch with my backup, does it matter which one I use (Backup #1 or Backup #2)?  My interpretation is that it does not matter since they both point to the same keys, but the encrypted keys on the backups have different passphrases, so they look different.

Sorry for being so anal about these distinctions, but sometimes they matter.

Thanks!

I would still wait for it to be imported.

Non-authoritative answer:
You can verify a backup at any time to see whether it could be imported. So when you've done that with backup #1, and Mycelium says the backup is good, you can destroy backup #2.

I'm new to the Mycelium Wallet.  It is a thing of beauty! Thank you.

I've read all 41 pages of posts in this thread, and did not see the description of something that is confusing me.

Background:
I have my wallet in expert mode, with two addresses that Mycellium created.  I made a backup, and the PDF has the encrypted private keys.  I recorded the password that was presented to me.  Let's call this Backup #1.

After playing around with the wallet for a week, I made a second backup of the same two keys.  I also recorded the new password.  Let's call this Backup #2.

Questions:
The two encrypted private keys look different between the two backups.  However the addresses on both backups are the same.  Is it safe to assume that the un-encrypted private keys are the same as well?

Now that I've made Backup #2, is Backup #1 still valid?  I am assuming that both Backups are valid, but I have to use the appropriate password with the two different sets of encrypted private keys.  If this is is true, I'd like to just get rid of my Backup #2 and stick with my original backup.  Can you please confirm that this will not be a problem?

Thanks!

Crosspost from Reddit:

Mycelium has been running the Indiegogo fundraiser for the Entropy device for a few weeks now, and we were really trying to avoid something like preorders (this was more of a fundraiser to see if there is enough market demand), and using BTC (due to issues others have had where the price of BTC skyrocketed while devices were delayed).

However, we have received tons of requests from people wanting to support us using bitcoin, so we gave in and added bitcoin links to our Indiegogo site. I have also included them here directly for convenience:

* $15 - Get a Mycelium t-shirt
* $40 - Get a Mycelium Entropy device
* $50 - Get a Mycelium Entropy device, and a t-shirt

We were overwhelmed by the success of our Indiegogo campaign. We set modest goals, to be sure to reach them and start producing, but we still need help and support to get these devices made. We will absolutely make sure that this project succeeds, and are even willing to use our own personal funds to get this project done, but anything extra we can get will help us a lot. We are still on target to start shipping by October. Since Indiegogo sends you the money as soon as you hit the goal, instead of at the end of the campaign (like Kickstarter), we have already transferred the money to our European bank account, and are in the process of negotiating the manufacturing order.

In other Mycelium news:

Mycelium will be at the Cryptolina conference in Raleigh, NC this weekend, August 15-16th, where I will be demonstrating our Mycelium Entropy device live, and **showing off the new BIP32/HD wallet feature in our Mycelium Wallet.** For those who don't know, this will allow you to back up all your bitcoin addresses using only one key (as opposed to making a separate backup for each address), and will make the wallet use a different change address for every transaction, greatly improving security and anonymity. This should also make managing addresses easier, and will allow us to implement CoinJoin for greatly improved anonymity (what DarkWallet uses) and make implementing the BIP70 Merchant Payment Protocol possible (which will make paying for things much easier, resolve some issues with who pays the fees, and help make 0-conf transactions more secure). We are getting really close to finishing it, and I for one am very excited.

if you have focus problems, try out the new beta channel release, there are new UI elements for controlling focus behavior.

Do you have "Autofocus" ticked in Settings?

So, Ive been testing importing private keys into mycelium via phone camera and noticed something. Mycelium wont autofocus =(
Is there any way this can be fixed?
Blockchain.info app focuses camera on QR codes just fine....
Mycelium wont attempt to focus at all....

wooohooo!

I really love mycelium, but I tend to re-use addresses (easy of use) and that behaviour needs to go out the window.

Almost there. Basic functionality is working in testnet. It just looks really clunky.

what's the status of BIP-32?

I'd really like to use my trezor with mycelium... ;-)

I did put that on the list of TODOs to consider.

BINGO my friend you hit the nail in the head, until you offer offline signing (hope), I will use your Bip38 way for the times I want to spend parts of my cold storage, At least this this is more secure then what I was using.

I have an Idea for offline signing You have a separate app, when opening this app it automatically puts your phone in airplane mode, this app also blocks ANY outside app from reading it or tracing it, once the signing is done it sends it to the Mycellium folder so when you open mycellium you select process offline transaction which pulls it from the folder and BAM done..maybe I am just dreaming here lol

My vote goes for expanding the bip38 import function to include the text.
(I used bit2factor.org to encrypt the key.)

I was able to decrypt the 6PRV address to get the 5Kar address using the given phrase. I used bit address.org on the wallet details tab.

Question
If you take the private key
5Karjv4pF57T9HFzqkS3Qe57KEhTAR1rfwF6YinWwcJJU8tAaci
and bip38 encrypt it with the phrase
crazy horse battery staple
You get the encrypted private key
6PRVsx6GBbcxgi2qoQ9GHAHAppRpX35Arv5eiJQet8GoPqPXCygYzYLL8G

Is that right?
