Calendar app from google not available I just upgrade my Samsung Galaxy s2 and was expecting to use the new Calendar app from Google itself. Here is a screenshot

It seems not to be included in the upgrade and strangely enough not downloadable from the play store.

I searched the net but it seems everyone can use it cause I see no similar reports. Is it available on your ICS android phone?

Thanks, Tom
That calendar app is the default included in AOSP. Carrier and manufacturer customizations frequently replace the AOSP variants in favor of modified versions.
This is what's happened with the Galaxy SII updates. Instead of vanilla android you received Touchwiz.

If you'd like it on your phone, you can install it from the Play Store or flash a custom rom like Cyanogemod or AOKP.
