ZTE's foldable, dual touchscreen smartphone - Axon M - launched earlier this month as an AT&T-exclusive. If you are planning to purchase this $725 device, you'll be glad to know that the carrier is now offering a $100 reward card with each purchase.

It's a limited time deal that requires you to purchase the handset on an eligible postpaid monthly service with voice & data (minimum $50/month). The reward card will arrive 8-10 weeks after service activation, and is valid for 6 months.
