AT&T have recently been sending out letters offering some wireless customers a free Cisco MicroCell™ — a letter they can redeem at a local AT&T store. I believe they’re doing this because AT&T want to buy loyalty from good but wavering customers. I was one such wavering customer, except I did not come by my free AT&T microcell so easily. Many subscribers got unsolicted letters for a free microcell. I had to argue for mine.
