iPhone Push Notification & WiFi Bug

This post is slightly geeky and more for my own benefit just in case I come across this problem again and need to fix it.

There is a bug in iPhone OS 3.0 and 3.0.1 that stops push notifications from working when the phone is connected to the internet over wifi. I could only ever receive push notifications when outside my home connected to the cell network.  Despite having cell reception in my home the very fact the phone had a wifi connection seemed to kill push.

The solution (and I have no idea why this works) is to manually change the iPhone’s wifi DNS settings to use a public DNS server (like OpenDNS) and not allow it to receive it’s DNS settings from the wireless router.

I changed this setting and the notifications flooded in!

No Power

The power in our house tripped during the middle of the night.

No idea what caused it but the end result is the power supply unit (PSU) of my main desktop PC now being non functioning.

This really doesn’t amuse me much. It’s about the only part on a PC I have no experience of replacing!

Meh.  Today was going so well too.
