    For CDMA, the number returned is the ABS(dBm). A value of 113 corresponds to
    -113dBm.

    According to GSM 07.07 Section 8.5, convert from dBm to rssi [0..31]:

    0 -113 dBm or less
    1 -111 dBm
    2...30 -109... -53 dBm [ (113 - s)/2 ]
    31 -51 dBm or greater

    To convert from rssi to bars [0..5]

    0 -113 dBm or less
    1 -111 dBm
    2...4 -109... -53 dBm [ ((rssi * 2)/15 + 1 ]
    5 -51 dBm or greater


    For GSM, I believe the number returned is rssi [0..31].

    0 0..3
    1..4 4..24 [ rssi/6 + 1 ]
    5 25..n

    (EDIT - bad math, couldn't get the equation to return a normal number)

    ahhhh, if I convert my RSSI value of 70 to a dBm level, then use that dBm level in the bars equation, on a 1-5 bar scale, a RSSI level of 70 comes to 3.867 bars on a 5 bar phone. Neat equation. Any math-heads reading who want to pull an equation out of that for 4 bar phones? (wait, does my treo go to 5 bars and i've just never seen it? lol)
