iPhone 5 may be significant redesign after all
The shipping product might arrive at the end of that same month, according to the tip.
What that design would look like wasn't mentioned but was previously identified as a teardrop-like shape. Some rumors have pointed to a larger, edge-to-edge screen. Others have pointed to a cross between the two.
The tip has partly been contradicted by Apple itself, which doesn't see iOS 5 shipping until the fall. Most every iOS device has been accompanied by a new software release and would be unlikely to ship on iOS 4 just before the upgrade was due to arrive.
