no. I used the download file. i click shift+update and select the .ipsw file 6.1

Hmmm .... that is weird, shouldn't there be a Shift + Restore button in iTunes? Sorry, I have not used this in a while so maybe iTunes 11 has changed the menu ....

my bad. I clicked the shift+update. will try to restore

Right.

From this site

"Once you’ve backed up your device, go ahead and restore to iOS 6.1. If history is anything to go by, I always recommend a fresh and clean installation when preparing for a jailbreak. Yes, you can choose to just do a simple upgrade, but make sure it’s an upgrade using iTunes, not an OTA delta upgrade using the Settings > General > Software update feature found on your device."

I'll try to do a update instead of a full restore. See can JB or not later

Wise advice you have there. Since iPhone backup is such an excellent system (much better than current Windows Phone 8 backup process), I also follow the same rule, I do a full restore (wipe clean) my iPhone, jailbreak and then restore my backup and synced my apps. This process has not failed me once and as the saying goes, if it ain't broke, don't fix it.

I want to update my iphone 4s using itunes.. But i dont know how to use it?
Do i need to use redsnow? Where i do i get the firmware?

Aiyohhh ... to update using iTunes no need to use redsn0w.

Download the firmware from this link ...

http://iclarified.com/750/where-to-downloa...ware-files-from

Select the firmware for iPhone 4s.

Once it finished downloading, open up iTunes and connect your 4s.

Press Shift + Restore iPhone .... a new window will open asking you to point to the firmware file you just downloaded.

Wait till it finished restoring your iPhone.

I would recommend however, before you do this to make a FULL BACKUP to the computer (via iTunes).

Then restore back to this backup after upgrade rite?

Really really thanks for helping me.. After this when jailbreak 6.1 release .. Can u help me with step?

Yeay finally 6.1.. Then jail break

Yeyyy..!!! I hav just backup my iphone 4s using itunes at my pc then update to 6.1.. Then i restore back using itunes and now my iphone 4s are now empty..! Yeyyyyyy.. Oh god..

When you restore the backup, there should be a list of backup files, iTunes usually create a Post-restore backup file as well (which will be empty), choose the backup file that is older than that (maybe a backup file that is 20 minutes older) which should be the backup file pre-restoration.

Yes.

OR

(I think this applies during the Absinthe jailbreak so not sure if it is relevant to the upcoming 6.1 jailbreak)

Wait until the jailbreak is out, jailbreak the phone after the jailbreak is released, then restore the backup

But if you cannot live with an empty iPhone, go ahead and restore the backup but as I mentioned in my reply to perrhhh, make sure you chose the proper backup file. The Post-Restore backup file will be empty, look for a file that is maybe 20-30 minutes older than the last file you see.
