    Can someone give me a primer on the pluses and minuses of going with the unlocked version of the SGS instead of the T-Mo Vibrant version? I saw a demo today of the Iphone 4 face time app and I like the FFC. I know we don't have concrete evidence that T-Mo has deleted the FFC. But, if they did I'd like the version with the FFC.

    Well we have no idea what the differences are yet if there are any.

    The only suspected differences from cellphonesignals image and original galaxy s is the front faced camera and 4 buttons instead of 3. everything else aside from those two things would be the same.

    If it comes to be that there is no FFC for sure, than could someone notify us on where we can find the Euro version?

    What are the chances that the EURO GS actually HAS the necessary bands to work with Tmobil's 3g network? Any chances that this phone is listed and marketed as a triband phone but really is a quad band phone that will support all GSM networks? This is my last hope b/c i am on tmobile but I want the euro version and not the "gimped" down USA version.

    That would be SWEEET....

    I was even thinking of buying an extra Euro version and swapping the Vibrants motherboard into it...lol.....

    hmmm....that actually dosent sound like a bad idea. If anyone has a teardown vid of the GS, i def would like to see it. If its anything like most of the other phones on the market, this would be as simple as plug and play.

    Here you go...


    YouTube - Samsung i9000 Disassembly.mp4

    At first I was thinking I could just find a spare front facing camera from a Euro version through a supplier online and install it into the Vibrant, however the front screen may not have the "clear hole" for the lenses to see through....lol....thus instead I am now thinking of putting whatever parts necessary (motherboard?) to get T-Mobile's 3G working from the Vibrant into a Euro version Galaxy S..then I will have a "complete" Galaxy S. Won't be cheap though.

    What do you guys think?

    :D

    I think this is very feasible. This is a great idea. I do not see why this wouldn't work. I would assume a re-flash of the roms would be needed (maybe) but thats a small issue. When i think about it more, i think your method will be just like swapping out a mobo in a pc. B/c these are essentially both samsung products, im assuming that everything will be compatible (same connectors and connections).

    One thing though, can you confirm that the radios are located in the mobo and not somewhere else in the phone?

    And as far as cost, i can think of a few ways to make the cost alot cheaper. If you can't think of any PM me and ill tell you what im thinking.

    Not sure what part controls the frequency bands yet...I did post this same question up on XDA Developers so hopefully we get some good info soon.....

    Hey... check out this tear down of a G1. Notice that the 3g components are all located on the Main PCB. Im not sure if this is a standard, but i have a feeling that it is. If so, a main PCB board switch between the vibrant and galaxy s should work.

    Okay, just did some more digging.....if you remember I posted a couple of threads about the full disasembly of the Galaxy S a while back, there was a video one and a picture one...well, the picture one shows a lot of good close-ups on all the internals of the phone, so I searched through it again and I found this:

    This was posted with these pics:

    有好幾顆都是TriQuint的RF IC,好像是分別處理900 1800 2100等不同頻率的訊號的。

    It shows proof that whatever controls the frequency bands is in fact on the motherboard/CPU.


    Once I disassemble my Vibrant I will compare the motherboard/CPU to the one in this pic....if it is exactly the same layout then my theory should work.

    I will be able to swap my Vibrant's CPU into the Euro Galaxy S and have a complete U.S. 3G enabled Galaxy S!!



    Think about this guys.....you can have the best of BOTH worlds....use the custom built Vibrant in the U.S....when traveling abroad swap the Euro CPU back in and use the phone out there......

    Would the different button layout on the Vibrant create a problem?

    I'm figuring there may be a few software adjustments needed but I think the devs over at XDA should have everything figured out by that time.

    Theoretically, if you use the vibrant's main board (which contains the 3g radio) in the galaxy s and re-flash a galaxy s rom on the custom unit, it should have no issues with butons b/c basically, it will be a galaxy s except it will be able to utilize tmobile's 3g signals. Please correct me if this is not logical.
