After the announcement on the 3G Iphone, I began to research whether Virgin Mobile USA had plans to change their network to GSM. I sent them an email. In response, they said that they do not support SIM cards yet, but apparently, Virgin Mobile UK has partners in the US (not Virgin Mobile USA) that support GSM. Virgin Mobile UK does support GSM, unlike Virgin Mobile USA. Who are these partners in the US with Virgin Mobile UK that support GSM? Do you think that I can get the same rates as Virgin Mobile with these other affiliate carriers?
