What is the gain for a wireless phone?
What part? Voltage or power gain? You need to be more specific.
If you mean antenna gain, it can range anywhere from about -3 to +5 dBi typically. dBi is gain over an isotropic source.
If you mean from the input (RF voltage) to the output (audio voltage) here's a typical calculation:
input at the antenna = 0.8 microvolts (typical for GSM phone)
output at the speaker = 250 millivolts
gain = 20 x log (250x10^-3 / 0.8x10^-6) = 109.9 dB
