Strange GSM/WCDMA problem after ICS update on Samsung Galaxy S2

[Toxin]

After waiting for my phone to update itself to ICS for a couple of days and even Kies not wanting me to update at all either, I decided to manually update by downloading the firmware from SamFirmware and using Odin.

Everthing went smoothly and the update is awesome..... except for one thing. Certain Apps on my phone doesn't want to connect to the internet. Speedtest, TuneIn Radio Pro and the MyGaming Apps give me connection errors. Even my Apps Store isn't working 100%. I can search for and download apps, but in the App description screen where the screenshots and clips of the app are supposed to be it gives me a "Couldn't load screenshots error. It's weird other Apps like Facebook and Gmail work perfectly.

BUT, if I switch and connect to a wifi network, everything works!

What could the problem be?

Go into your APN settings and delete everything except for the APN part which must be set to "internet" without the quotes.

And it's fixed! As easy as that.

Pleasure. This I learnt from a post by JannievZyl. Someone had a similar problem and he solved it. I am merely passing along the knowledge
