Hi - i wanted to insert a ATT gsm chip into my treo 270 which is basically unlocked international version.

I tried the chip in but it simply keeps searching for a network and does not recognize any aviable GSM network.

Pervioulsy i uploaded the GPRS international update would that affect my connection?

I called ATT and they said its problems with your unit - i doubt it as i have another SIM card for a service in paksitan and works perfectly there

Apprecaite any help/ ideas
