New cases are always a pleasure to see especially if they don't introduce old concepts. For example, Proporta's Doodle Pad Hard Shell case compatible with both the iPhone 4 and 4S alike - rather than the same old design that many other cases have, this option from Proporta boasts a new look that makes it worth the purchase in itself.
Sprint has launched a campaign to promote its mobile Wi-Fi device, Overdrive, and they're using the iPhone to help. The commercial features a hapless iPhone user, Steve, stuck with the slow and unreliable AT&T network, being helped out by a friend, Matt, who has an Overdrive (and an apple) in his pocket. As Matt takes a bite out of the apple, Steve is suddenly surfing on his iPhone much faster.
The details are still sparse, but according to Mac Rumors, AT&T's official 3G MicroCell web site is now up and running and users can get some quick video overviews as to what the finished product looks like.
