Engadget is reporting that both Radio Shack and Target will be lowering the price of the AT&T iPhone 4 tomorrow. They will re-price the iPhone 4 to $169.99 for the 16 GB model and $269.99 for the 32 GB model. The 8 GB iPhone 3GS will also be dropping to a $19.99 price point. 

This probably means one thing - Apple is planning a refresh for the iPhone, soon.

Anyone planning on making the jump or upgrading to the iPhone 4 when these prices become official tomorrow?
