Q: My itunes won't sync with my iphone

Close your iTunes,

Go to command Prompt -

(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".

(Win XP SP2 n above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt

In the "Command Prompt" screen, type in

netsh winsock reset

Hit "ENTER" key

Restart your computer.

If you do get a prompt after restart windows to remap LSP, just click NO.

Now launch your iTunes, Sync and see if it is working now.

If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

i did both of your solutions and still it doesn't sync . itunes stops at step 8 and it doesn't show my apps as taking any space of my iphone the capacity bar first show my apps then after step 2 they dissappear and on step 8 itunes freez ... please help !!

The above solution is meant for Sync stuck at Step 2 - Backup.

As for you, there are many resaons for Sync not to complete., e,g, corrupted Apps, Photos, music etc.

Can you stopped the sync now?

Whilst your device still connected, go to iTunes menu, FILE, Transfer your Purchases from iPad.....

If you managed to transfer your Apps, try do the sync again.

Another possibility of the issue is, you may have some Apps on your iPad that were purchased through a different AppleID?

i tryed what you said but it didn't work
i only use my appleID nothing is purshased from another ID
is there any other solution ? can i get a previous itune version ?

Try Start iTunes in iTunes Safe Mode:

1. hold down the Shift and Control key together and click to start iTunes.

2. You will get a popup that says "iTunes is running in safe mode. Visual plug-ins you have installed have been termporarily disabled.", click Continue to open iTunes.

You could already have your device connected to your computer or do it after opening iTunes in its safe mode.

Now press your sync button and see it works out OK this time.

didn't work :|

is there another way ?

thanks for your help

Lets try something here.

On you iPad, force close all the Apps in the multitask window.

Follow these steps to force an app to close:

1. From the Home screen, click the Home button twice. 
2. Tap and hold on the app. 
3. When it starts to jiggle, tap the to close it one by one until all cleared

Now do a Soft reset of your iPad:

Hold both Home and Sleep button for around 10secs until you see the Apple logo then release. After it returns to Home screen, connect to sync and see if this resolves the issue.
