AT&T Begins Selling $99 (Refurbished) iPhone
While AT&T has intermittently offered refurbished iPhones in the past, the $99 price point is noteworthy given the recent rumors that Apple was to introduce a $99 model. Apple's current iPhone starts at $199 for the 8GB model and $299 for the 16GB. The refurbished models have been discounted $100 to $99 and $199, respectively.
Analysts believed that dropping the starting price of the iPhone to $99 could double or triple projected sales.
