You will receive the wireless update in a few days or you can download the update file from here, and install it manually any time. The OTA server pushes the updates in batches, so not all users receive it at the same time.
i always flash using firmware upgrade cause i want a clean install... no problems for me... phone works like a charm.. just one question: did you disable the engineering menu?? i cant open it through *#*#3646633#*#*
I always test every solution in the following order if everything goes well.
1. Wireless OTA update
2. Flashing the same version with SPFT
3. Flashing back the older version
4. Manual OTA update
