@2c:
You're absolutely right. But here's the thing; the biggest telecom solutions are provided by motorola and ericsson. Nokia siemens just got into it a year ago and they're pretty new at this and they don't have any sort of infrastructure set up.
As for the chinese companies, huwawei and ZTE both suck. Wateen picked Motorola and Warid picked Ericsson- even though wateen was supposed to go with ZTE originally.
