Then select "weather" all the way at the bottom.
Click Account settings
There is your update frequency
One hour is the most frequent listed. I need shorter than that. Temp can change in lubbock tx 30 degrees in one hour.
-Email sync frequency: I believe the android google app doesn't allow you to change the sync frequency. The "Mail" app does (at least for exchange accounts). That is located in the "Accounts & sync" area.
Mail app has peak hours and days setting but i see no manual setting.
Adding one thing: If you setup your gmail account inside the HTC "Mail" app you can control the frequency it downloads (including manual download)
Same as above
Still no select all function though
Am I looking in the wrong place for email settings? I see setting for account, general settings, send and receive, and notifications plus delete.
