Really the only thing I rooted was to use the free Wireless Tether, which BTW came in hugely handy over my recent vacation to Portland. I've been following all the hype around Froyo, and now see a host of problems are having after upgrading with the OTA update. I like new stuff. I'm interested in Froyo. I have no doubt it will be long before it's rooted and I understand that PDANet works fine. I've used PDANet on Windows, Palm and iPhone, so I know that's good stuff. Worth the money, if the charge for it. I had multiple Palm and Windows Mobile paid versions. I understand there are some other apps that need root that are good, but I haven't used any yet. I tried JuiceDefender but I really haven't USED it to see if it helps with the deplorable battery life. So now I'm thinking I'll probably just stick with my rooted 2.1 for a while, because I'm really just not hearing enough good things about Frodo, ho hum.
