I have an iPod that when I try to update the Apps that are shown to need update-ding and when I indicated to have them updated I get a message "can not connect to App store". The ipod has been updateing until recently. I came still down load new App and

Question

I submitted my question but ran out of room in the box. I can still down load new Apps to my iPod touch AND update them but CAN NOT update the older Apps. that was on the iPod before the problem.
I have been to Three Apple Service Center stores - In Tulsa OK, Oklahoma City OK, Tacoma WA and NO ONE could tell me what is the problem OR what to do to correct it.  The Tech then tells me to get hold of the main Apple Service Center number. I tell them I already have and they still recommend going to them.
I have erased all information and started over as a new iPod Touch but the problem persists.
I have called the Apple Service number and they tell me to do everything that the the Tech's at the Apple Service center stores tried to do but DID NOT work.
After I spend a lot of time on the phone, I get told to make an appointment at a Apple Service center store so they can physically have hands on assistance. Come on folks I have already done that and they were of no help. When I say that, I get told that may be the only way I can get the problem resolved.
Surely there is someone out there that knows something about what is happening OR not happening with my iPod and provide a solution.
Thank You for your concideration
