Hi, I successfully jailbroke my device but I have a big problem now! I can`t use the mobile Internet I am paying for. I got the 3G Symbol up in my Statusbar (sometimes its white sometimes its blue). Phone calls and Wifi are fine. I spend hours and hours in the Internet and none of them worked. - Put simcard in and out - install Bossprefs, switch the 3G and Edge toggles and deinstall again - Use iphone Configurator and create a profile - restore mobile settings - etc. Please help me with this problem! I am using vodafone (in germany) and a have an iPhone 4 with jailbreaked FW 4.2.1 (greenpoison).
