Hi, I've got an unbranded Nokia N9, updated OTA to PR1.1 (20.2011.40-4_PR_009).

Ever since PR1.0, I've had a "Hidden Wi-Fi" shown in the network list. It is always visible on the phone, no matter the location. The network is not shown on eg. my laptop or my N900.

What is this network? Why is it showing? Is it a leftover from development?
