Best of luck to them, but 10 engineers won't cut it. Cellular modems are really complex, much more so than other processors. Frankly, there's a lot of black magic that goes into interpreting the specs and producing a chip that is going to excel on today's modern networks. Qualcomm pioneered the specs and have been doing this for a long, long time, which is why (so far) no other company has been able to produce a modem that performs anywhere near as well. Best course of action would be for Apple and Qualcomm to settle in an equitable way, likely both making compromises as necessary — or Apple should just lay out the money to buy Qualcomm.
