Ok I had a site bookmarked not to long ago, but can't find it. Is there any one out there that can help me out? Since AT&T's "4G" right now is simply HSPA+ in most areas. The iPhone can handle it, HSPA+ that is. With HSPA+ theoretical limit somewhere around 84 Mbps and real world average around 7-12 Mbps thats not bad. So what can each individual model for example 3G, 3GS, 4 and 4S handle?
