    Been looking for an app like Group Text for a while now. Thank you for making this!! I am telling all my friends. Can you make a group email app? :)

    Cro-Mag Rally is now updated for Retina Display on iPhone 4.

    It will be interesting to see how long it takes developers of existing apps to update their icons for the new hi- res display.

    They haven't even bothered to get to iOS 4 yet, lol, it will be a while.

    So apps that haven't been updated yet have low res icons? That's going to look strange.

    I wonder if Apple will release that Jenga game Steve was showing off the gyro with.

    ABContacts has both the features but it's more complicated because it has a lot of other features. I'm going to replicate the app for emails because I've understand that many users aren't interested in complex full featured apps but want simpler and easier ones.

    Thank you for using the app :)

    You won't notice as much as on the screenshot I've uploaded since the iPhone screen is half the size (and double the pixel density).

    They are low res in comparison to the new icons, but they will look pretty much the same as they do on the 3GS. I'd imagine they use a higher resolution mask for the corners as well, making the borders look the same.

    Vettori, when you developers update your apps to enable "multitasking", is it just a recompilation using SDK 4 or do you have to add in the API code?

    It depends on what a developer has to do with multitasking.

    My apps supports "fast switching". But even before iOS4 every time my app was closed, it saved the current state and next time it started on the same place. iOS4 has slightly simplified the process. It took me an hour to use fast switching in my apps.

    If instead an app needs to do something while in background, for example Pandora or Skype, then it is a bit more complicated.

    Even if all you want is Fast App switching, you still have to do a little bit of extra coding to support it.

    If one just recompiles the app, fast app switching works, but if one closes the app through the app switcher, or the OS runs out of memory and closes it, all the data you changed will probably be lost. Why? because app developers used to save the data when the OS told the apps they were going to terminate, but now when an app goes to the background, they never get that message. Once theyre in the background, the data should be saved.

    What app developers have to do is move the code from the terminate notification to the "going to background" notification, and the app will save like it used to.

    Hope that helps :p

    The Kindle app looks very good.

    It says optimized for the retina.

    Anyway, it's utility has increased considerably.

    EDIT: Sorry, I just realized that the app I linked to wasn't the same as the one from the keynote.

    That's not the app that was demoed at WWDC. This app doesn't even support the gyroscope.

    Paperless and it's free counterpart Paperless Lite both now have high resolution graphics (including over 300 icons) to take advantage of the iPhone 4's retina display.
