There are many ways to carry
a cell phone
on your belt
. Most phones
come with a belt-clip
that attaches to the back of the phone
and then to your belt
. The problem with those is that they tend to expose
the phone face
and (in some models) tend to break
The second option is to buy a cell phone cover. These are normally made of leather or something similar. They make your phone bulky and ugly.
The best phone holder I found is actually an FRS Radio holster, that you can buy at Radio Shack for ten bucks. You just slip the phone in there, panel facing you, and use a elastic band to grab the phone's antenna, holding it in place. It fits most small phones nicely, like the Nokias series 5 and 6, most Ericssons and many others.
