Do I have to actively do anything to avoid 2.1?
After 5 days or so on Sholes, I have no intention of going back. I've heard that Sholes 2.0.2 (the one I'm running, didn't upgrade to 2.0.3) blocks OTA updates so I won't have to worry about 2.1 installing itself and unrooting (or even worse, bricking) my phone.
I'll wait until whenever the Sholes team releases a 2.1 ROM to upgrade to whatever they have to offer since I'm so thrilled with how the phone works since installing this ROM.
Thanks for the info in advance.
