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

    1.  * Enter *#1546792*# 

    2.  * Choose Network and Call settings

    3.  * Choose Network Mode

    4.  * Choose GSM and hit Done

    5.  * If you need a password, it is *#81230#

If your calls still get dropped, please visit Cingular store and get a new SIM card.
