What Update Unlocked GSM or AT&T (formerly Cingular)?

[dotcommom]

I purchased a locked Cingular Treo 650 and then paid to have it unlocked so that I could use it with Tmobile.

My Phone Info states (Why is Firmware blank?):
Firmware:
Software: Treo650- 1.15-CNG
Hardware: A

When checking/installing the Treo 650 Updater do I use:
1. AT&T (formerly Cingular)
2. Unlocked GSM

Also, I need to apply updates found at the following address too but I am not sure if I should use AT&T (formerly Cingular) or Unlocked GSM.

Finally, any tips on updating my Treo 650? I have read that many have had problems after installing updates and would love to avoid them. Is there a certain proceedure or steps that I should follow? What should I do first, second, etc.?

Thanks in advance for all your help.

I would think that it is the unlocked GSM. I have not done this before but a call to t mobile should get an answer for you. If the right update is the unlocked GSm use new updates for that updater.

I am not sure if that updater (unlocked GSM) will work for t mobile. Have you done a search here for updaters t mobile??

Check out the link. This may help you. Then go to the palm site.

Thanks Plunker, Yes, I have done extensive searching on this and I have come up with mixed information that is why I asked it here. The link you listed basically just explains the differences between a locked and unlocked GSM Treo. It does not discuss which updates to use.
