IPhone 4S - upgraded to 5.0.1 and lost settings options

Question

Hi all,
I bought my first iPhone a couple weeks ago, an iPhone 4s with iOS 5.0.  After I activated it, I went through all the settings and option like any guy with a new toy.  I remember specifically that I was able to choose in Settings a) if, during a phone call, the phone would alert me to a new email or SMS with the tone I chose/vibrate, and b) if/when a reminder alert would happen after receiveing an email or SMS - I think the choices were 1/2/5/10/15 minutes.  I set these options as I wanted them - alert during a call and a 2 minute reminder.
Within a week or so, I noticed I was having battery issues like a lot of other people and saw that Apple release 5.0.1.  So I upgraded the software.  All went well as far as I could tell.  Unfortunately, this didn't solve the battery issues but actually caused some other issues.  Now, the settings for the two items I mentioned above are gone.  They are not in Settings at all and I really want to change them.  I've searched online and every page I find for the repeat alert tells me to go in to an area of Settings that doesn't exist any more in my phone.  So I thought, "OK I'll just downgrade back to 5.0 and that'll fix that."  But research here and on the 'Net says that I can't do that.
So I feel like I'm stuck.  I'm locked out (of sorts) of two options I really want to adjust in Settings and I didn't get a resolution for the battery drain.  Does anyone have any suggestions?  It's pretty disappointing; I like the phone, but I would love it if I could resolve this.
Thanks

Answer 1

I'll go backwards with my response.
Having restored my phone and reset all settings, operated phone as a new phone, didn't sync anything back onto it, etc., I installed only Tune in radion and it didn't play. I wiggled the dock cable about -the volume indicator kept changing and for a brief moment sound played. But, not for long.
I am thinking that there's something wrong with the dock connector.
Previously I had:
Checked all settings, plus switched off Bluetooth - didn't work.
cleaned headphone socket and switch on side which mutes sound - didn't work.
Restored the phone, without restoring any of my backed up data. Tested phone as a new phone - didn't work. Tried:
      voice memo - this was fine
      changing ring tones - this was fine
      playing a song from iTunes store - not ok.
      As a New Phone, installed one App - Tune In Radio - no sound. Get speaker icon at bottom, but no indication of its setting. When I click on sound mute on/off switch at side of phone, above volume controls, I see volume level, but can't control it.
Reset all settings, so had to switch of bluetooth again and re-enter WIFI. No affect on sound.
I've tried the above with and without headphones.
So, after much time wasting, my Music App and Tune in radio apps don't work, but ringtones and voice memo works.
