Then again, Akhavan might be wrong. Cisco and Nokia announced a dual-mode smart phone that can run on a GSM network (like the one Akhavan's T-Mobile operates) and over Cisco enterprise VoIP infrastructure. The Nokia E61i contains both GSM and 802.11g radios and can work on Cisco's Unified CallManager system. This, parenthetically, may be one of the things at the heart of Cisco's fight with Apple over the iPhone [1]. Cisco has said that all it wants in exchange for a license on the iPhone name is a promise that Apple products will adhere to industry standards. In plain English, that probably means Cisco wants the iPhone (which has a WiFi radio, remember) to work with Cisco's CallManager.
