Should my iPhone ever get a chance to be turned off?

No it’s not a problem; the occasional reset is needed only when the OS crashes from web browsing (very seldomly), I empty the cache from the Settings/Safari/empty cache command; usually crashes occur from cache memory filling up or from errors in the site/browser (e.g. a bad java script or other coding incompatibility).

Otherwise the only other advice I would give is to run the battery down to empty once a month (I actually set this as an event in iCal) to recycle the battery’s memory so as to prolong its life.

I agree with the above. I don’t think my iPhone has been off for more than 5 minutes since I opened the box. It is a good idea to run the battery all the way down (until it turns itself off) once a month or so. I usually try to do that with my laptop also, but admittedly I usually forget to do it with my phone.

thanx guys for the info!
