This is just a quick question Are the logic boards for the wifi and 3g versions the same? Common sense would tell you no but every teardown ive seen i try to compare them to find the difference and i only seem to find one, being a small black adapter peace on the end of the logic board on the 3g version that connects to the 3g module in the unit. This observation alone would have sufficed but when i went on parts websites hoping to get a closer look at the logic boards i only see one and its exactly the same for both wifi and 3g version which makes me wonder if this small black adapter piece at the end of the lb is soldered into the lb or is it easily removable/sellable. this makes me wonder further whats stopping a person from just obtaining this piece a sim card connector and antenna and simply modifying their ipad, other than cost.....................sorry for the ramblings and any thoughts on this would be greatly appreciated
