If statements/general help

Dear Unix community over the last couple of days I have been working on learning Unix scripting on iOS using terminal on a jail-broken device...
I am having trouble with if statements and giving the user a y or n choice that do different things when entered. The following is my code so far... Please tell me if you would like further explaining on what anything means or what i think it should do.
Thanks in advance,

Code:

#!/bin/bash
# iOS-Ad-Remover
# Marshall Ford @ marshallbford@ gmail.com
# This project is hosted @ http://ios-ad-
# remover.sourceforge.net
# Under the GNU GPL open source license
clear
date
echo
if [ `id -u` != 0 ]; then echo "You need to be root to run this script."; exit 0;
echo
fi
echo
echo "Welcome to iOS-Ad-remover Beta 0.1"
sleep 2
echo
echo "This script is similar to Adblock
in that it will remove ads from most apps,
some websites, and in Cydia."
sleep 1
echo
echo "You will need to meet the following
requirements..."
sleep 3
echo
echo "1. iFile installed and up to date"
sleep 3
echo
echo "2. The modified (hosts) file
that came with this script must located 
@ /var/mobile/Media/Downloads"
sleep 3
echo
echo "3. This script must be located
@ /var/mobile"
sleep 3
echo
echo "Have you completed the requirements
and still want to continue?"
echo
echo "y or n?"
sleep 1
read answer
# if [ "$answer" == 'y' ]; then
 echo "Backing-up"
 cd ..
 cd ..
 cd var/mobile/Media/Downloads
 mkdir backup
 cd ..

 cp fhosts /var/mobile/Media/Downloads/backup
 cd ..

 cd etc
 rm fhosts
fi
# if [ "$answer" == 'n' ]; then
 echo "Ad removal stopped by user."
 sleep 2
 echo "Good Bye"
 sleep 3
#end script

sensors(1)							Linux User's Manual							sensors(1)

NAME

       sensors - print sensors information

SYNOPSIS

       sensors [ options ] [ chips ]
       sensors -s [ chips ]
       sensors --bus-list

DESCRIPTION

       sensors is used to show the current readings of all sensor chips.
       sensors -s is used to set all limits as specified in the configuration file.
       sensors --bus-list is used to generate bus statements suitable for the configuration file.

OPTIONS

       -c, --config-file config-file
	      Specify a configuration file. If no file is specified, the libsensors default configuration file is used. Use `-c /dev/null' to tem-
	      porarily disable this default configuration file.

       -h, --help
	      Print a help text and exit.

       -s, --set
	      Evaluate all `set' statements in the configuration file and exit. You must be `root' to do this. If this parameter is not specified,
	      no `set' statement is evaluated.

       -A, --no-adapter
	      Do not show the adapter for each chip.

       -u     Raw  output.  This mode is suitable for debugging and for post-processing of the output by scripts. It is also useful when writing a
	      configuration file because it shows the raw input names which must be referenced in the configuration file.

       -v, --version
	      Print the program version and exit.

       -f, --fahrenheit
	      Print the temperatures in degrees Fahrenheit instead of Celsius.

       --bus-list
	      Generate bus statements suitable for using in sensors.conf. Such bus statements are only needed if you have  several  chips  sharing
	      the  same  address  on  different buses of the same type. As bus numbers are usually not guaranteed to be stable over reboots, these
	      statements let you refer to each bus by its name rather than numbers.

FILES

       /etc/sensors3.conf
       /etc/sensors.conf
	      The system wide configuration file. See sensors.conf(5) for further details.

       sensors.conf(5)
