You originally posted this thread on the GSM Hero section (although to be fair, it's not actually labelled the GSM section). Since your carrier is Cellular South, you must be using a CDMA Hero, so I've moved this thread to the Sprint (CDMA) Hero section.
So any advice you've read back in the other Hero section does not apply to your phone; your 2.1 update may work differently. Which is probably why you've had trouble with it so far.
