I downloaded and installed the Update pushed to my phone OTA.
It completely disabled my WiFi. "Unable to Start WiFi".
So, others beware that if you followed my guide of Flashing/Debranding your Orange Desire, WiFi will stop working if you apply the update.
What I plan to do is use the same Goldcard I created but install the updated ROM, found here :
RUU_Bravo_HTC_WWE_1.21.405.2_Radio_32.36.00.28U_4. 06.00.02_2_release_126984_signed.ex - xda-developers
My personal opinion is that, its going to be a real pain having to re-flash my phone everytime there is an update. My next flash will probably be to Froyo.
I will post back here the results!
