Yeah.
Seems like you can clone CDMA phones and clone the SIM for GSM phones.

The effectiveness of phone cloning is limited. Every mobile phone contains a radio fingerprint in its transmission signal which remains unique to that mobile despite changes to the phone's ESN, IMEI, or MIN. Thus, cellular companies are often able to catch cloned phones when there are discrepancies between the fingerprint and the ESN, IMEI, or MIN.
It doesn't really seem like a viable option anyway.

Yes, tethering the second phone might be the best option.
