Android phones, apps and tablets

I was using the HTC client to read my googlemail account. I like the way you can set it to sync at different times on peak and off peak etc. can't see any of the sync setting for the gmail app, unless I'm just being dumb. how often does it sync?

I've just borked mine. I'm trying to install it manually using the adb shell at the moment.
The r9 ROM I'm using won't auto update gmail. I'll have a look when (if) I finish.

I manually sync mine, for the record.
