The most expensive subsystem in the Torch is the LCD and touch screen display module section, at a price of USD34.85 (20.4% of BOM). Although market researcher iSupply was unable to identify the supplier in this case, RIM has worked with suppliers such as Samsung Mobile Display, Toshiba Mobile Display Co. Ltd. and Sharp.

Coming in at a close second in terms of cost is the memory subsystem, at USD 34.25 (20% of BOM). In this case, the supplier for the 4Gbyte eMMC NAND flash memory device, plus an 8Gbit NAND flash and 4Gbit Mobile Double Data Rate (DDR) SDRAM was Samsung. SanDisk supplied a 4Gbyte removable Micro SD memory card.



The mechanical/electromechanical portions of the Torch, including the printed circuit boards and the enclosure plastics and metals, came in third at an estimated cost of USD 23.35 (13.7% of BOM), the market researcher continued.

Marvell Technology Group, Infineon (the PMB5701 tri-band RF transceiver), STMicroelectronics NV (STV0987 video/image processor), Texas Instruments and Renesas were also able to score as suppliers.
