[whyhon]

I bought a 2nd hand unlocked treo 750. at the phone it's printed cingular but when turning off the phone it show vodafone screen. I believe my firmware is not the latest. if I want upgrade my treo at palm website, which category should I chose? vodafone, cingular or unlocked phone? will I make my treo to locked again if I upgrade.
software version:
TREO750-1.13-CNG
Firmware: 1.47.02.00
any sifu here can help?

You should be able to go to Palm website and download the desktop updater exe. that is made for Cingular/ATT phones. I believe they will ask you to enter the IMEI number before download which will identify the phone as a Cingular/ATT phone.

Your phone will not be locked once you do the upgrade and I believe you are refering to SIM unlock correct ?

So just go ahead and go for it and do what you gotta do

Whatever issue you run into its more than likely there is a solution here in this forum

OK, Done.
Thanks a lot

in case someone who needs. This tread explain how to flash original software from any branded treo 750 (ATT, CNG) to unbranded version (RWE).
