IPhone 3Gs OS 4.0.2 problems!!!

Question

Hi,
Thought my iPhone was the dogs danglies for 13 months until I made the biggest mistake ever of updating to the new OS4, how can this ruin the phone so much??
My biggest problem is now the loud speaker is very very faint, at first I thought it was a coincidence of the speaker going and updating, but as there is no warranty left on my phone and O2 insurance want £100 excess alone to look at it, I decided to replace the speaker module with a new one to find no difference.
So after loads of research on Google found that this is one of the problems of OS4 and as I never backed up my SHSH I can never go back to the faultless 3.1.3 OS..... SO p155ed at Apple, whats the point of a iPhone/iPod if the speaker doesnt work?
Has anybody else had the same problem with the speaker as me? Im booked into a Genius bar to see what they say on Wednesday, but im not holding my breath, cant wait for the barrel of ***** there going to tell me..
Regards
Gareth

And no he is not over reacting. I did the same thing. Trusted Apple that the upgrade was good. After five weeks of syncing not work king, tethering not working and battery draining after two hours at 60% I finally called Apple. Even though my 3Gs is out of warranty, they are giving me a support case at no charge. They got tethering working. They told me that the battery issue is probably due to multitasking. They showed me how to see what tasks are running.
For those or you who do not know; Press the home button twice. All the applications that are running appear. To close them, hold your finger on one of them until they start to 'shake'. You can close the ones you do not want by tapping on the red x on the top left corner of the icon of the application you want to close.
They solved tethering by enabling it in device manager on my laptop.
I can sync calendar and contacts. Notes will not sync. Apple support has now spent over four hours trying to get notes to sync. At one point they had me create a new user on my laptop. On the new user we set installed outlook and i tunes. I created one new note and synced successfully. But back at the original user it still did not work. I uninstalled outlook, renamed the pst files and installed outlook new. I entered one new note in outlook and synced. It did not appear on the phone. Apple had me delete the mobile profile, install new software and try again, oh and disabled avg anti virus and windows fire wall. No success. So now Apple has referred this to their engineers. They say they usually respond in 24-48 hours.
I know this is an issue for many people. So as soon as I have an update I will post it here.
