Hey
If you really want the jungles in your 1.1 worlds, you can trick the game to use the new generator by editing the level.dat file with a NBT editor.
The game looks for the tag called "generatorName", and if it's "default" it will also check "generatorVersion" (if it's available). If the version is 0, it will replace the generator with "default_1_1" instead of "default" to switch to the old generator.
To keep the new generator, change "generatorName" to "default" again and set "generatorVersion" to 1. Please note that this will mess up the whole biome randomizer, so it may start snowing in your desert if you're unlucky.

There may be hope?

This will be epic.
EDIT: They might even be adding Jungle animals *FingersCrossed

Jungle animals? *Throws up, from eyeballs, on my new shirt, in public, freaking out my friend, causing him to beat me up, making me sick, causing me to throw up, on my eyeballs*
