thank you.Your phone is quite different from a desktop. It has no moving/spinning parts. So the reasoning for turning the computer off at night for life longevity don't apply.
finally got the update. during update either i had left room for a minute and missed a prompt or it failed, as it had a msg that update mode failed. so it asked me to boot into recovery which i had never done before but was easy and it did the update.
only thing i guess i did wrong was i did not know it would take all my customized home screens and widgets and bookmark shortcuts etc and eliminate them.
so putting and guessing where they all were is a real pain but i did it. if someone has a suggestion for a program to prevent this for future that could put them back where you had them please do so. I heard there is a new backup feature in 2.2 but does it put homescreens back?
ps cannot comment on use of 2.2 yet as just did it, although playing around with the google speak bar is pretty cool.
