My father made a bet today.
1. He believes within the next several months, Apple will release an iPhone 4 with a changed antenna. That is, there will be a hardware fix.
2. He further believes that Apple will them offer some incentive to current iPhone 4 users to move to this new phone, such as $100 credit.
I could possibly see the first coming true, but very unlikely. If Apple decides to do a cosmetic fix (e.g., some version of duct tape over antenna gap), they could get that out in the next couple months, but that's not really the Apple way.
I think he's out of his mind with his second statement.
On a related note, does anyone know how I can get an iPhone in my hands?
