When I search on Ebay "Evo 4G" and it says for ex. HTC EVO 4G - 1GB - Black (Sprint) Smartphone (as one of the search results) Why is it only 1GB of memory? Wouldn't you like expect at least 8 or 16GB of memory or is that the ram I am very confused also if I bought a evo 4g with bad esn would that mean I could still get a sim card that has more memory than 1GB (Sprint).
