So i'm thinking of going back to the Apple Store today to see if they will exchange my iPhone for a new one.. My reasons are simple. I want a replacement one just to see if that solves the 3G issues i'm having. The latest fix did nothing for my phone i bought on July 20th.. If only 2% of iPhone 3G owners are affected by this could there be newer iPhones out there with better Infineon chips?? Would i be wasting my time trying to exchange my phone today simply based on the 3G issue?
