Thou shall tune your Blackjack
Default Blackjack settings from Cingular have the following problems:
- Battery life is short because frequent sync drains too much battery
- Dropped calls happen often due to network transition from 3G to Edge
In order to make your new Blackjack functional, you need to do the following:
- Get an extended battery from Cingular store if you don't have one already
- Turn off beaming if you don't need it
- Turn down screen brightness
- Change Sync interval to be 30 or 60 minutes. Instant sync will drain your battery very fast
- Force Edge/GSM, rather than 3G/WCDMA
- Phone calls get dropped consistently as network transitions from 3G to Edge
- * Enter *#1546792*#
- * Choose Network and Call settings
- * Choose Network Mode
- * Choose GSM and hit Done
- * If you need a password, it is *#81230#
If your calls still get dropped, please visit Cingular store and get a new SIM card.
