Dell is offering a limited-time promotion on the Motorola DROID X that will net customers a $25 Dell gift card. Through Dell’s online mobility shop, the Motorola DROID X is currently available for free with a two-year Verizon Wireless agreement. Dell is also waiving Verizon’s activation fee, shipping the handset for free via FedEx and offering customers one $25 Dell gift card per order. If there’s a sweeter deal out there for Motorola’s supersized DROID smartphone, we haven’t found it. Dell is also still offering the same deal on the HTC DROID Incredible.
