Fix: apps not working on 3G, but work fine on WiFi
This helped a couple of people on a Dutch forum, don't know if it's provider or country-related and if there even are users here that have these issues, but still wanted to let you know:
I have just fixed why some apps work only with WiFi but not on 3G. ICS apparently automatically added Proxy-settings to your APN, in my case Vodafone (NL). This is not necesarry to even make use of mobile internet, and it also prevents some apps from accessing the internet. I removed the Proxy-settings et voila, it works perfectly again!
Fix: Settings -> Press 'Mobile Network' (not Off-On!) -> Names accespoints -> Click your provider -> Remove 'Proxy' and 'Port'
Apps not working on 3G:
- Soccer Live Scores (developer mailed me this solution)
- Rabo Bankieren (dutch app)
- OV Chipkaart Checker (dutch app)
