Sync SGH-A707 Questions

I have a few questions that maybe some of you can answer:
1) Is there a way to have the main display show no clock at all? I know how to change the clock on the "Idle screen" option, but I don't want one at all.
2) Is there a way to have no shutter sound when taking a picture? There are options to change the shutter sound, but like the clock, I don't want it at all...
3) And Is there a way to make the AT&T words to go away from the main display? I'm figuring there's not a way since it's showing who I'm getting service from, but I figured I might ask anyway...
And that's all the questions I have. Thanks for looking!

1) I don't think so
2) No
3) I don't think so

biggie robs is right but, the phone is awesome.

1. Yes, instead of showing a clock, you can show the calendar. That can be done in the idle screen menu.
2. Yes, you can mute the shutter sound. It's a very involved process but here it is:

1. (on the idle/menu screen) dial *#0002*28346#
2. Press back (the top right ... button) 2 times
3. Press 6 ([6] YAMAHA)
4. Press 3 ([3] SP Vol)
5. Press 6 (6. SR[14] : 3)
6. Wait for the screen to refresh
7. Press 0 (to set the max volume (ringtone volume 7) to zero)
8. Press OK (the top left ... button)
9. Then get out of the menu (you could press the red button)

3. Nope, can't change the banner at all.
