Question

Dear Community,
Please, kindly assist me with following challenges. I use iphone 3GS. I have used the phone for almost a year now. My iphone 3GS cannot connect to the itunes store. Each time I connect my phone to my Laptop through itunes. A message will automatically come up which states that "iTunes could not connect to the iTunes Store. An unknoown error occured (306)". It also make a footnote which states "make sure that your network connection ia active and try again". When I click the button labeled OK just below the messages, another message will come up which reads, "A new iphone software version (5.1) is available for the iphone software. Would you like to download it and update your iphone now?". It gives me the option buttons such as CANCEL or DOWNLOAD AND UPDATE or DOWNLOAD ONLY. If I click on DOWNLOAD AND UPDATE or DOWNLOAD ONLY. Another message will appear which states that "The iphone software update Server could not be conted" With a Footnote that states "Make sure your network settings are correct and your network connections is active, or try again later.
The above challenge has continued for more that 3 months now. This challenge has hindered me from installing some applications like Facebook Application for iphone, LinkedIn application for iphone and a lot of other applications. Each time I try to get these applications my iphone 3GS while inform that my current ios version 4.1 cannot work with the application, that they requires at least ios version 5.1 or above.
Please, I really need your kind assistance. I am ernestly waiting for responses.

Dear Tim,
I saw your message. Below are the problems:
Whenever I connect my iphone 3GS to my PC through a USB. My itunes software comes up automatically.
1. After that a message appears from the itunes that states that 'itunes could not connect to the itunes store, an unknown error cccured (306).
2. After the above, an alert message comes up which states that A new iphone software version 5.1 is availlable for my iphone. It then states would you like to download it and update your iphone now? With the options buttons as Cancel or Download and Update or Download Only. Whenever I clicked on Download and Update or Download Only, the next message that comes up is that The iphone Software Update Server Could not be Contacted and suggest make sure your network setting are correct and active or try again later.
The above is the challenges I am facing now.
