One teen may have just achieved the dream of every cost-conscious wireless user: free, no-strings-attached mobile data. High school student Jacob Ajit claims to have discovered a trick that gets you all the T-Mobile data you want by using a proxy server. Reportedly, T-Mobile doesn't block sites with "/speedtest" in the address when you've run out of data on prepaid service. If you use the proxy to make it look like every site link has that text, you can surf to your heart's content at no charge beyond what it cost to get the SIM. Before you ask: sorry, folks, Ajit's proxy is down.
