The iPhone 4 is the same no matter where you buy it. All things held equal, one iPhone is indistinguishable from another. There is only one real way to “customize” an iPhone: the case. However, even in this regard you cannot completely customize any case.

Manufactures churn out thousands of the same kind of case in a bunch of different colors. Eventually, you’ll have the embarrassing situation of stumbling across someone with the same kind case. For real customization, in the sense, doing something to your iPhone, that you know will not be repeated by anyone else, you will need to hire an artist and do some high-end designing. This is a great way to create a truly unique iPhone 4 case, however, it can be extremely expensive (sometimes, even more expensive the iPhone 4 itself) 

Hence, Neostitch’s new line of customizable cases deserves extra attention. The case comes with small perforations that allow users to create a unique embroider design. This allows you to let your creativity flow, because you can create whatever design you like. The only requirement is a fluency in embroidery. This is no minor requirement though, since most people are not very familiar with embroidery.
However, it would be silly to simply dismiss this product right away because even though inexperienced average iPhone users cannot easily use it, it is a great option for those who are willing to spend a little extra and hire someone to create the designs for you. This is especially a great idea for companies that would like their logos or designs featured in iPhone cases (great marketing technique).
The entire system comes with 2 needles and 3 different colors of thread. The case also comes in a variety of colors including pink, blue, green and orange. You will be able to get your hands on the product for US$ 32. Keep in mind that you can get free delivery if you purchase it from Firebox.
