Device ID?

I downloaded and installed new software on my phone. To activate the application it asks for a 5 or 8 number Device ID? Where can I find the infomation?

Thanks

They must mean the pin (options / status / pin)...

I tried that and it didn't work. The message said the DeviceID specified is invalid. It is either 5 or 8 characters long.

Also when I went to the instructions it said the device ID can be found Menu, Options, About. I went there and did not see 5 or 8 digits.

i say try the esn # it is under the pin #
and naviwilliams showed you how

What's the software you downloaded / installed? Most applications want a pin number to associate with the software, thus provining that you're using the software with said device...

Problem solved. To solve the problem I went to the application support on-line, search support device id, opened the application and found the information. Whew!!!

Thanks again you guys are the best!
