I recently uploaded the new iOS6 operating system. My ipad worked fine until this morning. Watched video podcast, received early mail, but when I wrote 4 email messages I found them remaining in my inbox, and I was unable to get new mail, or to update facebook, or find webpages on Safari. Got the message 'server not responding.' I rebooted my wi-fi modem. Didn't help. Called wi-fi tech server. They couldn't find a problem. Wi-fi works on my computer and iphone. Checked settings. Wi-fi on and connected. Closed all apps, and re-booted ipad. Held down home botton and off button on ipad until the applea appeared, and waited. Problem remains. What else can I try?
I was unable to fix it on my own. My son suggested that I take it to the Genius Bar at an Apple Store. Fortunately I was going to be in the city, and was able to make an appt. with the store closest to me. A very helpful young 'genius' took my iPad in the back room and fixed it. I don't know what he did, but he said something about 'firmware'. I don't even know what firmware is, but he said it was unlikely that the problem would recur. There was a sense that it had to do with the new IOS6. If you are able to visit an Apple Store that is what I recommend. Make an appointment first online at Apple.com. The service is free and I was VERY grateful to have my iPad restored!
