Verizon Retail Stores Selling First-Generation Wi-Fi iPads for $299.99-$499.99
Verizon stores began selling the first-generation Wi-Fi iPad in late October, typically bundling the device with a MiFi mobile hotspot but also offering iPads on their own with no MiFi or data service required. With the launch of the second-generation iPad, Apple now offers CDMA models directly compatible with Verizon's network.
Late last week, AT&T slashed prices on 3G-capable first-generation iPads to $429-$629 with the carrier's online store dropping the 64 GB model even further to $529. As of this writing, AT&T's online store only has availability of 64 GB models at the $529 price point.
