According to IHS, the Lumia 900 contains no less than five Qualcomm ICs - a baseband processor, a Snapdragon applications processor, an RF transceiver, and two power management chips.
However all is not well in the offering of the other main supplier for the Lumia - Microsoft - which delivers the phone's Windows Phone OS.
It turns out that the Lumia 900 has a software bug which affects connectivity.
"A memory management issue was discovered that could, in some cases, lead to loss of data connectivity," says Nokia, ""this issue is purely in the phone software, and is not related to either phone hardware or the network itself."
Nokia's response? To give everyone a $100 rebate on their phone bill. The Lumia 900 costs $99 with a contract.
According to the IHS, the Lumia costs $217 to manufacture.
