iPhones have become important business tools. If nothing else, they offer a great way to check e-mail while you’re away from the office.

But the tool of choice for smartphone business users can always use a carrying case. We look at four here from UNIEA. Think of them as uniforms or costumes for helping your iPhone go to work.

At the top of the price line is the U-Suit Premium, built out of leather with an open face to use the phone while wearing the suit. This is the kind of dress-up you might want if you’re taking a new client to lunch and expect to answer a call, or make a point of checking a text during the meeting. I look ed the Intreccio leather, a classy grain pattern. You don’t get the sense that the iPhone is much protected here, but it adds a subtle, debonair look. $34.95 retail.

Next on the cost path is the U-Suit Hip Pop. Also built of leather, this belt-ready case has a tight profile against the waist. The cover has a clean magnetic snap to it (or at least it seemed magnetic, and sturdy.) The Hip Pop was my favorite in the rotation, since it was protective and made carrying the phone easier. The fit is a little snug, so this case might not be a good choice if you’re expecting to whip out the iPhone for calling. But the combination of function and design makes it among the best cases I’ve used. $29.95.

Another two cases came in the review pack, but at $19.95 retail these models didn’t show off as well. Read the rest of this entry »
