If you haven’t already heard, No Doubt is prepping a comeback and Gwen Stefani has given her solo career the boot. So it’s back to just being a girl with her band now. So what better way to celebrate than to dust off the spiderwebs of your No Doubt collection and snap on a new No Doubt iPhone 4 case. There are four No Doubt inspired cases by Case-Mate available for the iPhone 4, iPhone 3G/3GS, Samsung Galaxy S Vibrant, and iPod Touch 4G. You can choose the type of case construction, such as Barely There, Tough and ID. If you don’t happen to like the ready-made No Doubt cases, you can design your own No Doubt cellphone case with images and designs capturing the essence of the band. The No Doubt cases from Case-mate retail for $34.99 to $39.99 and will make you feel like you are living a simple kind of life.
