Apple has today announced that the iPhone 4 will now be available in Black and white for just $99. The iPhone 3GS in 8GB will be offered free with contract.

The announcement was made at the “Let’s Talk iPhone” event held at Apple’s Cupertino headquarters.

The iPhone 4 is identical in looks to the iPhone 4 that we know and love in almost every way. It will get the upgrade to Apple’s iOS 5 software, which we have tested extensively and can tell you runs beautifully, even on this ‘older’ hardware.

Moving the iPhone 3GS to a ‘free with contract’ pricing is an aggressive move by Apple that is solidly aimed at the cheaper Android market. It is an older phone but will still get iOS 5, making it an attractive alternative for those looking for the ‘cheapest option.’
