Basically, my iphone 3gs fails to turn on (this phone is relatively new). I tried holding down the power and home buttons at the same time, nothing happened. Then when I connect the iphone to my Macbook, the message says the phone is in recovery mode. After I attempted to restore, I received this message- cannot be restored, device isnt eligible or something. I dont understand the message but the phone fails to turn on, please help I am worried sick. (additionally, the battery is charged)
