I was updating my iphone 3G application and trying to sync new apps (deleting/adding apps). And my phone got completely froze. It only shows apple logo and never enters main screen. So I tried to restore the phone by pressing sleep and home buttons. Itune showed I have to restore the iphone so I clicked on restored. But it shows i can not restore due to unknown error 6. What should i Do!!! just take it to apple store? sux..
