All of those asking for the root exploit for the 2.1 OTA, or those unsatisfied with 2.1 and wanting to go back can now use this method posted by Droidmod. It is essentially an .sbf file that will install SPRecovery on the OTA update, and eliminates the need to downgrade back to 2.0.1 to get SPRecovery.
Once you have SPRecovery, you can just flash any new ROM that has superuser permissions. The link is here:

[mbm] was kind enough to provide this.
That should help people going from stock ESE81 OTA 2.1 get a root friendly recovery. No more downgrade, root, apply zip, install update fun.
Just flash that, and you will have the latest SPRecovery version installed.
Please note that this WILL reflash the boot image to stock ESE81! This is required to keep recovery from being overwrote on reboot. A few bits in the boot image were changed to break the checksum hash that the recovery update checks.
The md5sum of the image is:
9b6a336cd8f067d4487935468c758d89 SPRecovery_ESE81.sbf
PLEASE VERIFY THIS HASH! This is the ONLY way to verify that you have the correct image!
