I have an iPhone 4 and my girlfriend has a 4S. We've got the latest carrier settings, good 3G reception, and the majority of the time internet works great.

However, every few days or so, 3G internet will completely stop working for one of us. The only way to fix it is to turn airplane mode on and off again, or reboot the phone. Then it will immediately start to work again. When it's not working, reception is still great and the 3G symbol still shows in the status bar - phone calls and regular txt messages all work. However, data networking requests all immediately fail. Loading a webpage in a browser tells you that the site is unreachable, and no iMessages can be sent or received. It's almost as if the data network has kicked the phone off the network, but re-establishing a connection from scratch fixes it.

I was previously on Telecom and 2degrees and this never happened. I know Skinny piggybacks off the Telecom cellular network, but as I understand they're using separate networking systems on the back-end. It's highly annoying when you realise you haven't been receiving iMessages for hours with no indication that anything was wrong.

I've been with Skinny since they launched, and was hoping this was a tech issue that would eventually be resolved, but I'm thinking about switching providers if I can't find a resolution.

Is anyone else experiencing this, or can someone from Skinny please comment?

Thanks!
