I am sorry but I dont buy it either. These phones have been boxed and ready to ship out for a while now.
There is no way Sprint or HTC handed out 2,000 "test" units to the Google conference people. That would be suicide for both of them.
If RS alone has gone through 200,000 pre-orders there is now way from last week when the google people got their phones until the release next week that all those phones will be fixed.
I am willing to put money on it that if the google phones have this problem the phones next week will have this problem also.
On a side note: I have been using a 16gb card in my EVO for about 3 days and have not had the problem yet. Keeping my fingers crossed.
