This eris was purchased with v1.5 and updated to OTA 2.1 this summer. I read this thread "Can I root my Eris" and could not power down my eris to see the boot loader version. I tried holding the right button for 10 seconds but no dice. Any way, I have the 2.1 OTA and considering rooting my eris because I want to be able to wireless tether. Thanks in advance for you help!
