 This code not written by me. Thanks for unknown author.

<!--[if lt IE 7]>
<script language="JavaScript">
function correctPNG() // correctly handle PNG transparency in Win IE 5.5 & 6.
{
   var arVersion = navigator.appVersion.split("MSIE")

   {
      for(var i=0; i<document.images.length; i++)
      {
         var img = document.images[i]
         var imgName = img.src.toUpperCase()
         if (imgName.substring(imgName.length-3, imgName.length) == "PNG")

Upgrading Ubuntu Using the Alternate CD/DVD (Offline Upgrade)

Download the alternate installation CD from http://releases.ubuntu.com/oneiric/
Burn the ISO to a CD and insert it into the CD-ROM drive.
If the ISO file is on the computer to be upgraded, you could avoid wasting a CD by mounting the ISO as a drive with a command like:

sudo mkdir -p /media/cdrom
sudo mount -o loop ~/Desktop/ubuntu-11.10-alternate-i386.iso /media/cdrom

A dialog will be displayed offering upgrade using that CD then follow the on-screen instructions.

If the upgrade dialog is not displayed, run the following command using Alt+F2:

gksu "sh /media/cdrom/cdromupgrade"

Or in Kubuntu

kdesudo "sh /media/cdrom/cdromupgrade"

Jar file is over max size - Solved

The reason for this error is because the default value for a jar file in some phones are 400 or 500 KB. So when installation file is more than above size limit, you cann't install it.

To solve this:

1. In your keypad, type this code: *#52828378#
2. You will get the JAVA Test Menu after typing the above code, select the OTA Test menu and open it.
3. Then you will see the value 400/500 in Maximum JAR size field, change the value to a number higher than 400/500, i.e. 2048.
4. Save  and try to install jar files.
