Well done guys.
Having a HD wallet is a huge improvement. You guys always deliver amazing work and I am glad that I'm using your wallet! It might not look amazing, but it I couldn't care less about that. Keep it up guys!

Mycelium 2.0 Alpha with full HD support launched for testnet.
Over the summer we have been working hard to get Mycelium 2.0 with HD support ready. The Alpha version has been submitted for testnet and should be available on Google Play shortly.
The same signed APK can be downloaded here: http://mycelium.com/assets/btcwallet/mbw-testnet-release-2.0.0-ALPHA3build20003.apk
What's different?
At a glance it looks like it used to except that the Keys tab is renamed to Accounts, and all your keys/addresses are called accounts. So all your private keys and read-only addresses are preserved fully backwards compatible.
Beneath the UI everything has changed.
What is new?
TL;DR

Beneath the UI everything has changed.
What is new?
- When you click the + button in the Accounts tab you can create a new HD account. The first time you do this a master seed will be created. All HD accounts are derived from the same master seed using BIP44 account derivation. You can create your master seed from a BIP39 word lists (like with Trezor), or from an internally generated random number, or from an encrypted PDF backup (restore scenario).
- If you only use HD accounts you will only have to make one backup ever.
- An HD account automatically generates a new receiving addresses when you receive a payment to the current receiving address.
- An HD account automatically generates new a new change addresses when you send a payment that requires change.
- Transactions that you create while offline or with bad network connection get broadcasted once you go online.
- Transaction history is not limited to the last 20, and allows for seamless expansion when scrolling.
- You can put labels on transactions.
- You can have your classic single address accounts side by side with HD accounts.
- You can list the unspent outputs for all your addresses in an account. Nerdy feature, but nice to have now that your balance is spread over several addresses.
- You can have as many accounts as you like (HD or not), but your wallet will be slower if you have many. Since HD accounts produce unlimited amounts of new addresses as you use them you will eventually feel the effect. To mitigate that you can archive accounts as they grow heavy. You can activate archived accounts as you wish.

Thanks for the help .. what a great community 
So by a "cold wallet", or "cold storage" you mean a hard copy printout of the private keys?
What I am currently doing is regularly (once a month) converting some cash savings to bitcoin using ANXPRO, and sending the bitcoin to my multibit address. I keep backups of my multibit wallet. If I import my private key to Mycelium, will it be the same address as in multibit and if so what happens to the random address that Mycelium created on startup?
Can I import the multibit wallet directly into Mycelium or only the private keys?
Thanks again

If you import a private key from Multibit to Mycelium you will see the same balance and be able to spend from it in both places. This is however not a good idea:So by a "cold wallet", or "cold storage" you mean a hard copy printout of the private keys?

1. Instead of exposing your funds to one potentially compromised computing environment you expose it to two.
2. You may get confused as to why money went away from one wallet when spending from another.
3. You may cause double spends if you send from both wallets at or near the same time.
Instead I suggest that you have your Multibit address (not private key) imported in Mycelium, which allows you to observe, but not spend, the funds.
If you wish to spend from both wallets it is best to let them each have their own private keys.
If we are talking about savings and not 'beer money', then I would not have the funds online at all. Put them on paper and do cold storage spending:

You could consider abandoning the multibit wallet/address altogether. Do you really need it? Is that address likely to receive funds ever again? If not, just send the bitcoins to your new Mycelium wallet (once you know how to use it -- and be sure to make a backup of the Mycelium wallet so that if anything ever happens to your device, you can regain control of the bitcoins and move them to a new address).
As Onkel Paul says, for large amounts consider cold storage (and only keep "spending money" in the Mycelium wallet).

But be careful not to leave your private key unprotected, saved unencrypted, in unsecure or compromised computer, etc.
As he said, it's possible but not really advisable, at least not for significant amounts.
It makes a lot of sense to have a "small change" address that's shared by Mycelium and a desktop-computer based wallet, so that whenever you want to spend a little bit you can do so regardless of the device you use. But for larger amounts, you should minimize the risk by keeping the private key away from any unsafe places. Use a cold wallet.

Hi,
I am very new to bitcoin.
Is there any simple documentation available explaining Mycelium for those of us who are just starting out?
My first basic question is ...
I currently have a multibit wallet containing bitcoins. What's the easiest way to tell Mycelium about my multibit wallet? If I then get BTC sent to my bitcoin address, I assume it will be reflected in both multibit and Mycelium.
Thanks
Andy

There is good link to help (Q&A) in the Mycelium application itself.
You can add your multibit address into Mycelium as watch-only (therefore anything sent to this address will be reflected there, but you would not be able to send BTC from this address by Mycelium).
Or you can export corresponding private key from multibit and import it into Mycelium (and you can then use this address both in multibit and in Mycelium). But be careful not to leave your private key unprotected, saved unencrypted, in unsecure or compromised computer, etc.

Do you you have a guess at when HD will be released? I can't wait to try it.
This was answered two posts above 
We hope to get the testnet version with HD out tomorrow./quote]
Oh, thanks. Sorry, when threads get this long I don't read every post. I usually look for updates in the OP or ask someone that posts like they're in charge.
So if I install the new apk, all personal data from the old apk are preserved?
Yes. But make sure to have a backup nonetheless. Edit to clarify: do not uninstall the app, install the new one on top of the old.

I don't use googl play. How can I avoid losing all my data when installing/updating the new apk?
We always upload the latest signed builds here: https://www.mycelium.com/bitcoinwalletWhen you update everything is preserved. However, this is no excuse not to make a backup

v1.3.3 was released to Google Play store, github, and our site.
The list of changes from last regular release include:
* Generic scan button in the main view - Use this to quickly scan QR codes to send bitcoins. In the future, this may be used to quickly log into websites with BitID.
* Improvements to barcode scanning with flashlight toggle and autofocus setting
* Email notifications for LocalTrader - Google Push Notifications system is still kind of unreliable, and we can't fix it because it's Google servers that are having issues, so this is a fix until we figure out something better.
* Fixes and connectivity fallback for dns issues - A few days ago we had an issue where our domain name, which is pointing to our servers, was temporarily turned off by our provider while they verified that we are who we say we are. Should this happen again, wallets will switch to contacting our servers with their IP numbers directly (this is also likely temporary, until we move everything to Tor)
* Various crash fixes
We think that this will be the last feature update for the non-HD version. Stay tuned for an upcoming Mycelium HD release.

When can we expect to get the HD mycelium? I just recently discovered the benefits of using an HD wallet. Because of this I had to switch from using mycelium to another mobile wallet. I really like the mycelium UI and would like to switch back.
Very soon. It's basically functional in testnet at this point, but still has some bugs to iron out, and to be implemented in LocalTrader correctly. It will probably be out by the time Mycelium Entropy devices ship.
We hope to get the testnet version with HD out tomorrow.
Central server? What is this referring to?
Just the way Mycelium works.
I'll be impressed if you get it to work! I would have thought that the architecture of Mycelium, where the central server keeps track of your "savings", made this impossible. How could the server know which addresses to track? It might be possible, just difficult, but that's a challenge for you guys..!
I don't see how this is difficult or even "impossible". Mycelium asks the server for the amount in XYZ address. Simple.
Right, it's how lightweight wallets tend to work. I did notice, in contrast, that Wallet32 evidently downloads some portion of the blockchain. I don't know if this process is also centralized or not, but I found it different from other lightweight wallets.
Yes, we do not keep some kind of user accounts on our servers or something like that, they just create structures for optimized search in the blockchain, allowing the clients to ask for balance, transactions, etc very efficient. While there is of course quite some work to do on the server side as well, its not a general problem for the infrastructure to support HD wallets.
This is what I was getting at. Thanks!
