With Verizon poised to take a big bite
of its smartphone market share, AT&T has decided to slash the price of the iPhone 3GS
. The company is currently selling
the smartphone for $99, but, beginning Friday, both new and existing customers will be able to purchase it for just $49. (The iPhone 4 is still selling for $299.) The obvious downside, however, is that buyers will be locked into a two-year plan... with AT&T.
