  6. Upgraded to OS 4.0 and jailbroke with redsn0w. Did the unlock with ultrasn0w and carrier and signal will come up (Fido) but will quickly lose signal to "no signal". I've tried many methods with airplane mode and rejailbreaks but nothing seems to work. If I am lucky I can get one call in before it will eventually drop service. It is an iPhone 3G by the way. I don't know what else to do. Any help?

  7. I am having 3GS iphone. It is used in UK with vodafone n/w. Now it has brought up to India. When i was updating the itunes unfortunately i upgraded from 3.1.3 to 4.0 and base band changed from 05.12.01 to 05.13.04 Again i degrade my iphone to 3.1.3 by restoring itunes. Now it is in factory setings. Now the problem is the iphone is struck on the connect to itunes and emergency call screen.

    Below shows the error message throwing on my pC when i connect to itunes. Please suggest me how to get rid of this issue. Thanks in advance.

    The SIM card inserted in this iPhone does not appear to be supported.

    Only compatible SIM cards from a supported Carrier may be used to activate iPhone.

    Please insert the SIM card that came with your iPhone or visit supported Carrier’s store

    to receive a replacement SIM card.

    1. Jailbreak it? If the sim card isn't an official carrier then that is your only option. Use redsn0w and I would update back to 4.0.

    2. Hay Venugopall, did you fix your problem ???.. I too have the same issue please lemm know how you fixed.

      Thanks in advance.
