Meh. I got all excited when I saw the cydia update for the blockchain app. Turns out its an unrelated bug fix and still broken on 5.1.1.

Is Blockchain.info using this crc16 method or otherwise vulnerable to this?

Honestly I'm not sure. The standard Yubico SDK is used and both the public and secret key part is checked. There has not been any security updates to the SDK recently so I assume it is ok.
how many blocks does this: http://blockchain.info/q/hashrate look back? might be interesting to give the look back as a parameter.
does it go across retargets?

It uses the 24 hour avg difficulty (~140 blocks) and it know consider re-targets.

thanks.
should you ever get bored a good difficulty estimate would be nice
Is it possible to make unconfirmed/orphan transaction not count as "available" balance for an address?
for instance http://blockchain.info/address/13TcJozDQMXPatGS8ZdzXnzezLMjxe5DS6
the 4.43922435 BTC balance are all orphaned blocks.

I see that Blockchain.info uses both Mt. Gox yubikey and Yubico's yubikey. There's a potential security issue using the default authentication method which uses crc16 and thus a valid looking authorization token can be obtained without having the AES key.

Ok thanks, got my iOS 5 jailbroken and believe I have found the issue.
I'm looking forward to the fix. I had been wanting to send some coins the last few days and using my phone is by far the easiest way; I missed it.EDIT: and the security doc looks good. I wasn't expecting the site to be running on 3 mac minis. Just 1 small thing, "CSFR" should be "CSRF"
Balances in the sending or receiving address book? Can you point me to an address where there is a discrepancy between block explorer and blockchain, might be a bug.
example:https://blockexplorer.com/q/addressbalance/1HostFatgTXWdRmVoneC8M6ErhiuQ7An5o
It showes: 2.0936819
http://blockchain.info/q/addressbalance/1HostFatgTXWdRmVoneC8M6ErhiuQ7An5o
It showes: 209368190
That is perfectly ok: addressbalance/Address - Get the balance of an address (in satoshi)

Important question to Ben

Haha thanks. I'm just passionate about bitcoin.
For 5.11 jailbreak i believe Absinthe v2 is best at the moment.

REQUEST:
It would be nice to be able to view the current balance / total received / total sent of all adresses in the adress book, kind of like in blockexplorer (it seems blockexplorer and blockchain.info calculate differently).

Scheduled Maintenance
My hosting provider has informed me that scheduled maintenance is planned for the 1st and 2nd. Although they have allocated 6 hour window I have been informed the downtime should be longer than 15 minutes.
Security Overview
After the recent bitcoinica incident I've been thoroughly reviewing the server side security at blockchain. Obviously blockchain has a fundamentally different security model to bitcoincia but regardless no chances are been taken.
Although cloud servers are great for many reasons I think the Linode/Rackspace incidents have proved when it comes to handling sizeable sums of money there are just too many variables beyond you're control to be secure. Blockchain.info runs on privately owned dedicated hardware, a Brief overview of the setup is available below and I'm happy to answer any questions.
http://blockchain.info/security_overview.pdf
I have the blockchain app installed and have imported a whole list of vanity-adresses for some purpose or other.

Could you add an API which returns the minimal data?
You can add a limit 0 parameter to address results e.g.
https://blockchain.info/address/126vMmY1fyznpZiFTTnty3cm1Rw8wuheev?format=json&limit=0
Does that still contain the information you need?
Perfect!
I didn't see this limit in the docs (at least not where I was looking).
is http://greenpois0n.com/ the genuine unlock tool?

Here is very nice jailbreak wizard for all iOS devices:

I've received a few reports of the iOS app crashing using the new 5.1 jailbreak. I'll look into it soon, is http://greenpois0n.com/ the genuine unlock tool?

So I've added a new page to Anubis to retrieve balances from blockchain.info. All I display is BTC received, sent and current balance. The rest is wasted bandwidth for us both.

I haven't been able to get the blockchain app working since I upgraded my iPad and 4s with 5.1.1 and the absinthe JB. Is anyone else having this problem?
It's been mentioned in another thread
So now that 5.1.1 is jailbreakable untethered for the 4S, I went ahead and updated. The app store version was working except the profile page didn't have my email or settings in it (only the wallet identifier was shown). I uninstalled the app store version and installed the Cydia version, but it crashes immediately. Any ideas?
The Cydia app is working fine for me, but I'm still on 5.0.1 (iPhone 4). I was going to upgrade to 5.1.1, but I've started using the app more and I don't want to update if it's not going to work.
Wait to upgrade; the Cydia app isn't working for me either.
Thanks. Sorry you had to be the guinea pig on this.

Is it possible to request data through the API on an address, but without all the tx's?
That's quite a lot of data there I don't need.

Which call are you using?
Just what it say in the API doc...
Currently: /rawaddr/$bitcoin_address
The other (/address/$bitcoin_address?format=json) prints the same.
