Hi, I downloaded an application from iTunes called Viber. I synced my iPhone but I couldn't complete the operation because a message appears telling me that "it requires a newer version of iPhone software" On the other side of it, I look at iTunes and it tells me that my iPhone software is up to date. I have software version 3.1.3 How do I update my iPhone software in order to get Viber, if I apparently have the latest software? Thank yo, kind regards, igmolinav : ) !!! My iPhone is a 2G and as far as I know, 3.1.3, is its lates version.
