I think that the problem is here:

We were able to clearly identify some cellphone signals that originated from on board the aircraft [again, see chart, "Cellular Stands Out"]. Ours was a conservative estimate, since a call made at the other end of the cabin from the instrumentation would be below the threshold we could observe. Our measurements also found emissions from other onboard sources--devices used by passengers--in the frequency used by GPS.

The only flying I've done was between countries in Europe, so I can't say how it is for other airplanes, but the seats closer to the instrumentation are for the business class. That would mean that the people who pay more for flying should have the most restrictions applied to their devices. What are the chances of that happening?

There was only one report, and it was for a phone that is was longer in manufactured at the time of the report.

The Samsung SPH-N300 is a CDMA dual-band mobile phone. Samsung has advertised that the model was the first mobile handset with built-in E-911 capability. This technology helps to identify the location of the handset using a built-in GPS receiver, but with additional assistance from the network to overcome deficiencies in low signal strength areas such as inside buildings. The handset has menu options to allow the E-911 feature to be turned off to protect users privacy. The SPH-N300 model was no longer in production at the time of testing, thus a previously owned unit was acquired from an internet auction site for this study. This particular unit defaulted to the Personal Communications System (PCS) band upon registration with a local wireless network, and had logged approximately 150 hours of previous airtime use.

There is no evidence that modern phones cause this problem.
