I am nervous about the official ICS update by T-Mobile. Apparently they shut off Wifi and/or Wi-Fi Tethering. Is this true? I have an unlimited data plan and I am not on a contract. T-Mobile is full of nonsense and it is saddens me to see how companies are becoming more greedy than ever before and it will only continue to get worse. At least they don't charge for GPS usage like AT&T does.
