I recently went on vacation and my phone was turned off the whole 2 weeks I was gone. I got home 3 days ago and charged it and it seemed to be working fine. Then I got an incoming call and the caller was unable to hear anything I was saying. I tried rebooting it. I tried resetting my network, settings and the phone and it still didn't work, so I took it to the place where I purchased it and they told me to synch the phone before I send it away as I will loose everything that's on there. So I did this and my phone didn't synch and now when I click on any app that uses the internet my screen goes blank and it goes back to my home page! I have tried synching it several times and it only synchs for 2 seconds and says it's done. All of my app logos are still on my phone but none of them work except for the ones that came with the phone! I am waiting till I can get to an Apple store on the weekend as I'm not paying for a loner phone because it's ridiculous that it is 200 dollars! But in the meantime how do I get my apps back in working order? Help me please!
