Hi Guys,
I know that there are several threads on this issue, but I just need to start a new thread on this problem.
I have tried upgrading my OS from 3.2.1 to 4.2 three times but on all 3 occasions, after the download is completed and installation actually started, it stopped and report "Connection Lost ..."
It is a huge file to download for a start.
Any help .. I desperately need the upgrade as some of the apps that I have purchased only works with the new OS.
I am on Kaspersky Internet Security, Window 7 Pro, and Broadband connection.
Please .. please help me.
Thanks .. John

Disable all virus and firewall.
Do not run anything else (there may be programs running in the background) before it is finished.

Then try again, and again.
You will get ther finally.

Hi,

Will update you as soon as I have succeeded.
Again, thks for the suggestion.

Go to iClarified - iPhone - Where To Download iPhone Firmware Files From and download iOS4.2.1 for iPad and install manually. Shift-click on Updates and point iTunes to the file you have downloaded and it will update your iPad with it, instead of trying to download it from Apple.

I had the same issue some time ago and the solution I found (maybe it was even here!) was to delete your temporary Internet files and then try again.

Do you have Wi-Fi Sync installed on your computer? It will keep you from being able to upgrade and restore any iOS device!

iOS 4.2 is a little different from previous iOS updates because it brings the iPad inline with the operating system version running on the iPhone and iPod touch. That means that iPad users finally get to try out multi-tasking and folder management for apps, just like iPhone and iPod touch users have been doing ever since iOS 4 was first released. This also marks a change that at least some iPad owners won’t be happy with: The iPad’s rotation lock switch is changing to a mute switch to match the iPhone. There isn’t any way for users to decide which feature they prefer, but at least the rotation lock is still available through the less convenient software switch, just as it is on the iPhone. iOS 4.2 is compatible with the iPad, and all but the first generation iPhone and iPod touch models. Some features like multi-tasking aren’t available on the iPhone 3G or second generation iPod touch, and HDR photo support requires an iPhone 4.
