I've always kept the GPS and the DATA power on the power widget flipped on. I would turn on BLUETOOTH and WIFI as needed. During 2.1, the GPS would activate only if I opened an app that required it, like Google Maps. But since 2.2, I've noticed the GPS running for no apparent reason. No open apps, no open browser, no open maps. Nothing. it just runs on it's own. An it only started since 2.2. I've never had to shut off my GPS before, but now, I have to keep it off and turn it on as necessary. Very frustrating. Anyone else having this problem?
