OK so I punch in the reserve battery code *3370#
Nothing happens, I reboot with the numbers up nothing happens?? What am I doing wrong?? I thought the phone was supposed to reboot itself with that code??

    Where in the world did you come up with that?? There is no "reserve battery" in an iPhone and no such code.

    Yes there is punch it into your phone & it will come up with reserve battery mobile.
    All mobiles will activate a reserve battery with this code.

    Nonsense. The iPhone has only 1 battery. If I enter that "code" all I get is an error message.

    Saying "all mobiles will activate a reserve battery with this code" is patently ridiculous since "all" mobiles have different designs. If fact, I don't know of ANY current cell phones with reserve batteries.

    I have 2 that do. My 3G show under the number "Battery Reserve Mobile." Don't believe it if you don't want dude.

    I know for a FACT, that there is no reserve battery in iPhones. If this code really works, why are you posting that it didn't for you, and now suddenly contradicting yourself. It doesn't work for anyone, except for your instantaneously increasing imaginary collection of iPhones.

    My 3G show under the number "Battery Reserve Mobile."

    That just means the number has been stored in the phone's address book (maybe copied from a SIM that had been in another phone). That doesn't mean it does anything.

    "CLAIM: Press *3370# to access 'reserve battery power.'
    False. On some Nokia phones, users can punch in special codes and toggle between speech codec modes to 1) enhance voice transmission quality at the cost of diminished battery performance, or 2) enhance battery performance by decreasing voice quality. Apparently, some users have misconstrued the latter as "tapping into reserve battery power." On that score the email is doubly erroneous because *3370# is the code for enhancing voice quality, so using it actually decreases battery life!"

    This certainly doesn't involve "activating a reserve battery" (as the OP claims) in the Nokia, and nothing whatsoever with an iPhone.
