I was finally enjoying some sweet fantastic LTE speeds at work today and had my Galaxy tab tethered to my Galaxy Nexus when I got a phone call. On my old Epic this use to make my data connection drop out, but, wonders of all wonders! I continued to surf the web, with no apparent drop in speed as I conducted my phone call! I remember reading that this might be possible, but was pleasantly surprised to find that it was, indeed, a fact.
