Help Connectivity Issues Since Ice Cream Sandwich Update

[newkicks]

My wife and I have been forced to update to Ice Cream Sandwich 4.0.4, reluctantly, and now have major connectivity problems.

Phones will not connect to 4g, 3g is at a snail's pace and wi-fi is in and out...usually requiring a power cycle to connect.

Anyone know if there is any way to:
a) uninstall ICS an reinstall the old OS that worked just fine
-or-
b) install some patch or update with bug fixes, etc.

Any info is appreciated. Good info will hold you in the highest graces.

Tanks y'all!

Go here to roll back to old OS:

I had a system update on my Samsung Galaxy S2, and now that I've done the update, none of the screen displays change (the light for turning on and off GPS, WIFI, battery strength indicator, bluetooth, etc.) Also, the voicemail indicator widget no longer shows when I have a message. Also, regarding my media player the artists/songs no longer display, and the play/pause button doesn't change. My message indicator light also no longer lights when I have an email/text/etc. HELP!?!?

Called sprint today about problem. They say the store repair department has a newer version of OS that they can install but it won't come OTA. Sounds fishy to me but my wife is taking phone into store today to see if that solves problems.
