    I switched my Treo 270 from T-Mobile to ATTwireless. I can't get it to register with the ATT Network. It seems to do an endless search.

    I bought the phone on E-Bay and it was unlocked. I can't imagine the T-Mobile guy locked it when is stuck the SIM card in.

    What do I need to do to get it to work with ATT Wireless?

    I figured it out. I had to go to PalmOne and upgrade my GPRS to the ATT specific GPRS. Even though I had updated GPRS, it was not the ATT Wireless version. My phone now works great on ATT Wireless. I'm not sure why I had to do this just to get phone service as opposed to data service, but, it worked.

    You could have probably just changed your network setting... but you would have to know the ATT parms.
