    Hi all

    This is my first post so excuse the seemingly simple question, but I can't afford to render my phone obsolete))

    I have an iPhone 4 Version 4.3.3, Firmware 04.10.01 and a Gevey Ultra Sim Card. The phone works fine, but I'm a little apprehensive to upgrade to version 5. There are various step by step guides, but I'm no IT pro and would appreciate any advice moving forward.

    Much appreciated :)

    Who's your carrier? You could always purchase an IMEI unlock.
