A Verizon iPhone is coming but may not have the world roaming some users would want, Northeast Securities analyst Ashok Kumar claims today. After contacting Apple's suppliers, the researcher believes Qualcomm has landed a deal to produce a CDMA iPhone but that it won't be a dual-mode phone with both CDMA and GSM and consequently can't leave North America with cellular service intact. BlackBerries like the Storm2 and Tour have such features themselves.
