Does the new iPhone 3Gs need the 7.2 Mbps in order to be up to twice as fast? According to AT&T, they have not even deployed this speed increase. There would definitely be no reason to upgrade if the 3Gs is not going to be 2x faster out of the box. Speed of loading web pages is a major selling point for me. I understand that the faster processor would open apps faster but would we see a difference in web browsing? It's probably the 7.2 Mbps they are waiting on to deploy MMS and Tethering. Read info below from AT&T web site. NETWORK AT&T operates the nation's fastest 3G network, delivering the power and benefits of mobile broadband to consumers and businesses. iPhone 3G S will be compatible with High Speed Packet Access (HSPA) 7.2 technology, which offers theoretical peak download speeds of up to 7.2 Mbps, though actual speeds will vary as these capabilities become available. AT&T plans to begin deploying HSPA 7.2 later this year, with completion expected in 2011.
