I waited 2 weeks to get my Treo working in data although a supervisor in support was nice enough to set me up with temporary data service that had to be logged on and off. Now that the phone signs on with the user name the little data arrows are there all the time (grayed out in voice and no data transfer). It seems that the battery is going down a lot faster, I have not tried disconnecting in my network prefs after going on line but was wondering if:

The little data arrows are supposed to always be present (green when in use and gray when not).

If leaving the phone connected to the network draws more juice from the battery even if your not accessing data.
