When I downloaded the ipsw zip, I dont see any ipsw file. What am I supposed to do?
Mobile Blog Team says
Just change the extension of the downloaded file to .ipsw. Seems that you have used a download manager to get the update. Use the normal browser based method to download iOS 4.2.1 ipsw of your choice, and it will work.

For Restoring the downloaded image in iTunes 10.1, i used the key combinations (Command and Option key) + click the Restore button.

You have to backup your iPod Touch apps, settings to iTunes before updating to iOS 4.2.1. Just right click on the device icon (on left pane) and backup.

Hi,
after I download the iOS 4.2 update towards my ipad I couldn’t listen to certain streaming audio like I used to such as radiotime.com. When I try to listen to a certain radio station, the station would work intially then then the HTML 5 player would load but then a message would read HTML Stalled. Now I can’t listen to any radiostations. I assume this is the same with all iOS 4 (my ipod touch 4th generation would read video can not be played. IF you can still find a 3rd generation ipod touch and would like to listen to radiotime buy it and don’t download the new iOS 4.2.1! Also the locking feature has been disabled and the screen has become very sensitive to rotation, if you’re watching a movie it’s going to drive you nuts.
My ipad had 3.2.2. and everything worked fine. If you still have 3.2.2 don’t upgrade to iOS 4.2!!!
This is a step back to apple.

Eugene says
You all need to do proper research. You are all too eager to use your iphone yet you do not want to research at all:
@Ben – Get proper internet connection
@Badal…download proper ipsw file again. Do not use torrents
@ym…there is nothing like passkey. What are you downloading?
