I have a new iPhone 4S and I am unable to get apps because there is no app store installed on the phone. I purchased the phone brand new. In settings App Store exists but it is not to be found anywhere on the phone. I have tried to download a few apps I would like e.g. Skype and I get a message saying "Safari cannot open the page as the address is invalid." Please help. I am new at this and I do not know of anyone else who has had this problem, and I am unsure if I am just missing something simple. Thanks.
