Latest T-Mobile ad ridicules AT&T network, touts 4G superiority

Fancy Carly's new attitude? Then you might be interested in checking out the latest T-Mobile commercial, which shamelessly ridicules AT&T and its wireless network. In particular, the 30 second video aims straight for the iPhone 4S (which technically isn't a 4G smartphone, by the way) and attempts to convince you that HSPA+ on a T-Mobile 4G smartphone delivers much higher mobile data speeds. The advertisement is part of T-Mobile's shift in marketing strategy. Carly is not that nice skirt-wearing lady we once knew – instead, she prefers leather jackets and riding her mighty magenta motorcycle now.
