T-Mobile releases their latest campaign video with "Ms 4G" taking a stab at the iPhone 4 on both the Verizon and AT&T network. Claiming to have to largest and faster 4G network nationwide, T-Mobile clearly identifies that if you fancy an iPhone 4 you aren't going to be going anywhere fast, at least with 4G.

On January 6, 2011 Philipp Humm made his first public appearance as president and CEO announcing the plans to upgrade the T-Mobile 4G network by doubling the speeds as well as releasing 25 new 4G devices. T-Mobile is clearly making a point that they want to be the leading 4G network with the most devices available to its users. Will "Ms 4G" still be smiling after the other carriers finish their 4G network infrastructure? Watch the video and let us know what you think.
