Assuming that the _licensed_ amateur could modify the phone enough that it _could_ operate on frequencies allocated for amateur use. The only thing that would be potentially close is a European GSM phone: Rx Tx E-GSM-900 880.0?915.0 925.0?960.0 MHz R-GSM-900 876.0?915.0 921.0?960.0 MHz T-GSM-900 870.4?876.0 915.4?921.0 MHz & the US amateur band at 902 - 928 MHz. I don't think any of the CDMA phones are close enough to the amateur bands to have a hope of working - but I'm not as familiar with CDMA as GSM.
