Really, then why would, if rumours are correct Apple be:
"iPhone: The fifth-generation iPhone may be set to launch as early as January in order to address antenna issues with the iPhone 4. "
If there are no issues then Apple won't be doing this. We shall see.
If we accepted rumors at face value that Apple is really late with their Verizon iPhone which people have been swearing up and down will be released for years now.
Until they pan out, they are just rumors and are pretty meaningless.
