So I upgraded to an iPhone 4 today. I have an iPod touch and wanted to transfer all of my apps from the iPod to the iPhone.
I was able to set up the iPhone fine and all the apps seem to have transferred, but all the data is gone. For example, Angry Birds has lost track of all my level progress (and I've done A LOT) as well as not realizing I've already purchased the Eagle add on. The inception app no longer recalls which dreams I've unlocked.
The weird thing is that Game Center remembers all of my achievements. I'm guessing the game data that tracks level progress/ unlocks is somewhere on my iPod, and I'm wondering if anyone knows any way to transfer that information to the iPhone.
Any help is really appreciated!
