In one embodiment, a method includes accessing data encoding a response shift in a signal received through an antenna of a mobile device. The signal corresponds to wireless communication to the mobile device from another device. The response shift is detected and encoded by a modem of the mobile device coupled to the antenna. The method also includes determining an environmental or operational state of the mobile device based at least in part on the response shift encoded in the data.

1. A method comprising: by a computing device, receiving a signal through a first antenna that has a first resonant frequency, wherein the signal corresponds to a wireless communication to the computing device from another device, wherein the signal has a peak amplitude at one or more frequencies;by the computing device, accessing data encoding a frequency response shift corresponding to interference in the received signal, the frequency response shift being detected and encoded by a modem of the computing device coupled to the first antenna;by the computing device, determining an environmental or operational state of the computing device based at least in part on the frequency response shift encoded in the data; andby the computing device, in response to the determination of the state of the computing device, swapping a function from the first antenna to a second antenna based at least in part on the frequency response shift, wherein the second antenna has a second resonant frequency, and wherein a difference between the second resonant frequency and at least one of the one or more frequencies is less than a difference between the first resonant frequency and any of the one or more frequencies. 2. The method of claim 1, wherein a source of the interference comprises an object coming into proximity or contact with the computing device. 3. The method of claim 2, wherein the environmental state comprises one or more of: the computing device is in physical contact with a user;the computing device has been placed in a pocket; orthe computing device has been placed on a table. 4. The method of claim 1, further comprising by the computing device, initiating a pre-determined function of the computing device in response to the environmental or operational state. 5. The method of claim 4, wherein the pre-determined function comprises resuming operation of the computing device in response to physical contact with the computing device. 6. The method of claim 1, wherein the wireless communication substantially complies with a Global System for Mobile Communications (GSM) standard. 7. The method of claim 1, wherein the environmental state comprises one or more of: the computing device is at a work location;the computing device is at a residence; orthe computing device is at a public place. 8. One or more computer-readable non-transitory storage media embodying logic configured when executed to: receive a signal through a first antenna that has a first resonant frequency, wherein the signal corresponds to a wireless communication to a computing device from another device, wherein the signal has a peak amplitude at one or more frequencies;access data encoding a frequency response shift corresponding to interference in the received signal, the frequency response shift being detected and encoded by a modem of the computing device coupled to the first antenna;determine an environmental or operational state of the computing device based at least in part on the frequency response shift encoded in the data; andin response to the determination of the state of the computing device, swap a function from the first antenna to a second antenna based at least in part on the frequency response shift, wherein the second antenna has a second resonant frequency, and wherein a difference between the second resonant frequency and at least one of the one or more frequencies is less than a difference between the first resonant frequency and any of the one or more frequencies. 9. The media of claim 8, wherein a source of the interference comprises an object coming into proximity or contact with the computing device. 10. The media of claim 8, wherein the wireless communication substantially complies with a Global System for Mobile Communications (GSM) standard. 11. The media of claim 8, wherein the logic is further configured to initiate a pre-determined function of the device in response to the environmental or operational state. 12. The media of claim 11, wherein the pre-determined function comprises resuming operation of the device in response to physical contact with the device. 13. The media of claim 11, wherein the environmental state comprises one or more of: the computing device is in physical contact with a user;the computing device has been placed in a pocket; orthe computing device has been placed on a table. 14. The media of claim 8, wherein the environmental state comprises one or more of: the computing device is at a work location;the computing device is at a residence; orthe computing device is at a public place. 15. A device comprising: one or more antennae; andone or more computer-readable non-transitory storage media coupled to one or more of the antennae and embodying logic configured when executed to: receive a signal through a first antenna that has a first resonant frequency, wherein the signal corresponds to a wireless communication from another device, wherein the signal has a peak amplitude at one or more frequencies;access data encoding a frequency response shift corresponding to interference in the received signal, the frequency response shift being detected and encoded by a modem coupled to a first one of the antennae;determine an environmental or operational state based at least in part on the frequency response shift encoded in the data; andin response to the determination of the state, swap a function from the first one of the antennae to a second one of the antennae based at least in part on the frequency response shift, wherein the second antenna has a second resonant frequency, and wherein a difference between the second resonant frequency and at least one of the one or more frequencies is less than a difference between the first resonant frequency and any of the one or more frequencies. 16. The device of claim 15, wherein a source of the interference comprises an object coming into proximity or contact with the device. 17. The device of claim 16, wherein the environmental state comprises one or more of: the computing device is in physical contact with a user;the computing device has been placed in a pocket; orthe computing device has been placed on a table. 18. The device of claim 15, wherein the logic is further configured to initiate a pre-determined function of the device in response to the environmental or operational state. 19. The device of claim 18, wherein the pre-determined function comprises resuming operation of the device in response to physical contact with the device. 20. The device of claim 15, wherein the wireless communication substantially complies with a Global System for Mobile Communications (GSM) standard. 21. The device of claim 15, wherein the environmental state comprises one or more of: the computing device is at a work location;the computing device is at a residence; orthe computing device is at a public place.
