Google's closest response to the iPhone 4 on AT&T was rolled out today and turns out to be a relatively low-end device. The HTC Aria has Android 2.1 with multi-touch and Sense UI but scales back compared to higher-end world phones like the Legend. It has a 3.2-inch, 480x320 LCD instead of an AMOLED display and uses a five-megapixel camera without a flash.
