AT&T chose not to let Verizon's iPad deal go unanswered today and said it would carry the iPad in its own stores on October 28. The original iPad supporter will stock only the existing 3G iPads rather than the Wi-Fi plus MiFi combos at the rival carrier. Its plans remain the same and give 250MB of monthly, prepaid bandwidth for $15 or 2GB for $25; iPad buyers don't need to sign up in-store.
