    Default iPhone 3G 4.2.1 bb 16.5.00 no 3G :(
    Heyy, hope I can find an answer on this website..

    I have a jailbroken(redsn0w) and unlocked (yellowsnow) iPhone 4.2.1 bb 16.5.00. I can make phonecalls, write sms's, surf on my wi-fi but just can't access either edge or 3G ! When i boot my phone i'm able to access 3G for about 10sec but then windows just stop loading and have to reboot.. The little 3G logo continues to be "on" but just won't WORK

    Please help

    You install Ultrasn0w to unlock bb 6.15, yellowsn0w is only used to unlock bb 02.28.00 of firmware 2.2
