    So, you got an iPhone 4. It was a cheap eBay iPhone with no power and you're wondering if it's worth fixing. The front screen is destroyed and the phone has no power. It was next to nothing anyways...

    You heard about the way to do it, remove the motherboard, remove the sheilds off the MB, and identify the samsung memory chip, enter the serial number from that then you got the gb...but no need to take your iPhone apart! Read on.

    Well, It might be general knowledge around here but I'll post it anyways.

    HOW TO IDENTIFY GB with an iPhone 4 that has no power:

    Remove the two (2) bottom pentalobe T5 Torx screws that hold the rear battery door glass on the back of the phone. Slide it up and remove it.

    There is a serial number on the LCD connector EMI sheild cover, on the iPhone 4 CDMA and 4S GSM.



    **On the iPhone GSM, the serial number is located on the right side of the battery well.**

    Ok, most of you are telling me, "idiot! I know that. So what!"

    Hold the phone, I'm not done yet...

    Read the last 4 digits of the serial number. It is the clue to tell you whether you have a phone worth fixing, or a phone to use as a paperweight.


    Read this graph to identify what gb your iPhone is!

    Now, if, by now you're telling me "You retard. That is so general knowledge around here!" Well, if that's the case, I guess I am a retard. A big fat retard. But, you tell me, is this general knowledge here?

    Hope this helps somebody because it helped me! ;)

    If you don't need the GB, you could use the fact that:

    3 antenna 'splits' = iPhone 4 GSM

    4 antenna 'splits' and no SIM tray = iPhone 4 CDMA

    4 antenna 'splits' and SIM tray = iPhone 4S

    Though yours is a good guide if you need the GB as well.
