As reported here last month, AT&T is now sending e-mails to some iPhone customers who are at or nearing the end of their contracts, offering a free home 3G microcell (a $200 value) in exchange for staying with the company for another year -- in an effort to keep customers from switching to Verizon. 9to5Mac reports on a user who recently received the e-mail offer, showing the company making the offer "as our way of saying 'thank you' for your continued loyalty."
