As many of you maybe know on 10/27 T-Mobile lost its´exclusive Deal with Apple. Since then 2 other Carriers are offering the iPhone 4, Vodafone and O2. I am using O2 now for 2.5 years and I am really happy with it. Good 3G coverage nearly everywhere I am, reasonable prices and a very friendly customer service.
But with the new IPCC settings when O2 became an official iPhone Carrier, my Tethering was gone. But guess what, new IPCC this night and voila it works again. Happy Happy Happy Happy.
