move a US Cellular TP2 to T-Mobile

[danhux]

I have a US Cellular TP2, I'd like to move to T-Mobile. T-Mobile says they can't help me until the CDMA settings will change in network settings to GSM. My question is, what do I have to do to be able to change the setting under "mode of operation" from CDMA only to GSM? I've been messing with this phone for about 4 days off and on. I've learned a great deal about WM, cell phones and cell phone networks. But,, not enough. This phone doesn't have a SIM card in it. My new TP2 from US Cellular doesn't have a SIM card under the battery. My son has the TMobile SIM card he wants to put in the older US Cellular TP2. What am I missing? I got mighty rom loaded, it works great. Any help would be greatly appreciated.
