The 12C application was updated already. However...
The 12C application did have 2 versions. This was due to a technical problem in the very early version that was in the Apple app store. We were unable to ever update the first application due to a change in Apple's app store backend, so Apple told HP to sumbit a new version to the store.
One week ago, after working with Apple for over a month we were finally able to update that original version after the did some tehcnical things in the store for us. We then updated the ORIGINAL application and renamed it to HP 12C Legacy (and raised the price to something ridiculous so nobody new would buy it and instead find the currentl 12C application)
Both official HP 12C apps have now been updated! You should be able to get your update if you check for updates through the app store on your iOS device.
HOWEVER - there are many people who though they were purchasing the official HP one. They bought something called 12C Lite, 12C Financial Calcualtor, HP12Pro or many other variants. There were many, many counterfeit HP 12C apps in the early part of the app store. Most of those have since been abandonded or removed.
If you DO feel like you purchased the correct, official HP unit, you should now have your update. If you don't, you'll need to verify with apple that you DID purchase either of those two and in your current account.
Although I work for the HP calculator group as a head developer of the HP Prime, the views and opinions I post here are my own.
