OK... I just performed a claim because i lost my S3 with MetroPCS. They tried to give me a Samsung Mega but i declined and said i dont want that so... THEY ARE SENDING ME AN S4!! The S4 will be for MetroPCS. I made sure they are sending me the GSM model (because when i paid $600 for the S3 they gave me a dang CDMA model) and I will not active it through MetroPCS but through TMobile instead (Way faster 4G) Which thread will i be using to root and flash ROMs? The MetroPCS threads or the TMobile threads? I do not have the model number as of yet because i'm waiting for the phone but i know that will help clarify things. I am excited and want to get all the stuff i need to root and flash so that its done within the hour of receiving it Thanks in advance!
