1)Ext2,Ext3 are external partitions you create on your sd card in order to link or move apps from the phone and free up internal memory.This is the case for Eclair(2.1) or lower only.
2)Froyo onwards,there is a native apps2sd which would automatically be able to move apps to the FAT portion of your sd card which means there is now no need for any partitions to be created and not recommended either.
As you can now see,point 1 above is born out of necessity arising from the inadequacy in the older operating system!
Trust this clarifies.
