App installation on external storage media
The Android platform now allows applications to request installation onto the device's external storage media (such as the SD card), as an alternative to installation onto the device's internal memory.
Application developers can express the preferred installation location for their applications by means of a new attribute of <manifest> in the manifest file, android:installLocation. The attribute supports three values: "internalOnly", "preferExternal", and "auto". At install time, the system checks the value of android:installLocation and installs the application .apk according to the preferred location, if possible. If the application has requested external installation, the system installs it into a private, encrypted partition in the external media. Once an application .apk is installed externally, the system lets the user change the storage location of the .apk and move it onto the device's internal memory if needed (and vice versa), through Manage Applications in the user settings.
By default, the system installs all applications onto the device's internal memory, except for those that explicitly request external installation. This means that the system will always install legacy applications onto internal memory, since they do not have access to the android:installLocation attribute. However, it is possible to configure and compile a legacy application such that it is installed internally on older versions of the platform and externally on Android 2.2 and later platforms, if necessary.
Note that requesting installation onto the device's external media is not suitable for all applications, particularly because the external media may be removable and unmounting/remounting may disrupt the user experience and system settings.
where is this 2.2 information coming from? is it confirmed by google or is someone tweeting it saying that this is what they heard by attending google IO?
if the latter, where can we check for a confirmation by google?

Not sure if we allow embedding of youtube videos on this forum so link to official 2.2 video. Someone can embed it later if it is allowed. Um never mind it did it anyway............ *tumbleweed*

if your phone was launched this year, we will most likely offer an upgrade for it to the Froyo version. This includes popular models like the Desire and Droid Incredible as well as hotly anticipated phones like the Evo 4G, MyTouch slide and upcoming models. We will announce a full list of phones and dates once we are closer to launching the upgrades.
At least you are going to get an update! It's only 2 months to the second half of 2010, although it could also be December!
It should be on the nexus one first, until they don't get it, we won't have it I guess. pop into the N1 forum n see what they saying. I am following it with attention.
...well the Desire forum that is
There's more traffic in here than the Nexus forum, lol.... if your phone was launched this year, we will most likely offer an upgrade for it to the Froyo version. This includes popular models like the Desire and Droid Incredible as well as hotly anticipated phones like the Evo 4G, MyTouch slide and upcoming models. We will announce a full list of phones and dates once we are closer to launching the upgrades. We are working closely with Google and our other partners to ensure we have the earliest access to everything we need to provide a complete and solid Sense experience on Froyo. We expect to release all updates in the second half of this year but can't be more specific yet.
post this in the official android 2.2 discussion please guys..
