This is an engineering problem, nothing else. I'm ignoring things like space in the case as that doesn't matter. Like I said, the android phones don't have an antenna inside, they do it with the headphone jack, which the iPhone doesn't have. The problem isn't with space but interference. Induction charging causes minimum interference with radio frequencies (it's a magnetic field, which affects radio signals but only at a very close distance with the power levels used and generally not too terribly so) . Plus you aren't going to be wirelessly charging and using the phone actively for the most part, and if you do it still has the advantage of an IP network and data re-transmission and error correction. This isn't true with general FM radio. When you have such a powerful transmitter antenna right next to a low power receiver, along with the analog signal, with no means of error correction, it's going to create a LOT of interference and distortion making it almost unusable. You would have to completely turn off the LTE/GSM/CDMA for the FM radio to work if the antenna was in the case. If you really need emergency alerts in an area where you don't have cell coverage you are NOT going to depend on a phone. You'd (like I do) have a dedicated, device with recharging capabilities since you don't want to stake your life on a secondary feature on a device with terrible battery life.
