Hello,
I have a Blackberry 8120 Pearl, OS 4.5, T-Mobile provider, no data plan.

When I choose Wi-Fi only and am connected to Wi-Fi, the phone can still send and receive calls. As I understand the settings the phone should NOT be connected to the T-Mobile Network. When I am out of Wi-Fi there is no phone connection.
Worked about two hours with a T-Mobile tech rep and could not prevent phone action. We wiped the phone clean and did a reinstall of the OS, and calling/receiving was verified.
SETTINGS:

Options>Mobile Network>
Data Services= ON
Connection Preference=Wi-Fi Only
Mobile Network=T-Mobile
Network Selection Mode=Automatic

Manage Connections>
Mobile Network=OFF
Wi-Fi=ON
Bluetooth=OFF

If anyone is knowledgeable of this and can advise how to turn off the phone connection would appreciate the info.
Thanks,
