maybe you know how to disable a cell phone jammer

Indeed you can. If you want to interfere with GPS but still want to talk on your phone, you need to use a gps jammer. This device is blocking all GPS signals in its work area so the A-GPS module on your Sprint CDMA phone will not work. Even if the A-GPS module starts to work, it is completely useless without a GPS signal to find your location, and A-GPS only speeds up the process.As for the phone, I would recommend that you continue to use your CDMA phone as GSM phones often combine the A-GPS modules with GSM modules into one unit.

 As long as you need to bring the interfering device to the office, it should be small and portable.The same is true for all types of webcams, Bluetooth speakers and other Wi-Fi or Bluetooth-based devices.However, as long as the Wi-Fi network is very fragile, it is unlikely to be used in the office. Therefore, your prank ideas may work and you can try, but it is entirely your responsibility and you will face angry colleagues.This is why this small Bluetooth jammer is most suitable. It can be used without attracting everyone's attention, and it is powered by batteries.You can learn How To Disable A Cell Phone Jammer.
