Other than not getting the benefits of Froyo that is? I haven't done it yet and I am seeing a lot of "wish I could go back to 2.1" and "Froyo destroyed my battery" posts on here so I am weighing my options. I love my phone and it works well. My battery is great (usually around 24 hours with light to moderate use) and everything is just the way I want it. As I understand from the myriad posts on this board if I update I will probably have to go back and check all my settings again, possibly factory reset (with all the fun that entails) and possibly lose some of the functionality I currently have -- all for a flashlight app a little speed improvement and flash. Am I missing something? On the other hand, if this is something I will really need to do (eventually if not now) to keep my phone current and continue to get new apps, I want to consider it. Those of you who have had a bad experience, have the "fixes" on here mostly done the trick? I am willing to go through all of that if I get my phone back at the end of it all, but will be really upset if I do all this and my battery is cut in half or worse. I already BTDT on the Moment with the 2.1 upgrade so I am skittish.
