Picked up my Defender case this morning from Best Buy. I'm a Conservation Ranger for Georgia State Parks and wear a duty belt at work so I'm constantly having to rig something up to hold my cell phones on the belt because it's so wide (2.25"). Otterbox makes a heavy duty holster for many different defender cases that come with a larger clip to accommodate the duty belt. I contacted OB a few weeks ago asking the possibility of them making an optional duty belt holder for the new iphone 4 defender and they said at the moment there weren't any plans. Long story even longer I had a heavy duty clip at the house from my old Bold 9700. Upon investigating the clip mechanism I quickly learned that it had the exact same internals. You would have thought the OB rep would have known this and I even asked! I removed the HD clip from the Bold holster and it is a perfect fit!! So if there is anybody out there that wants the new OB Defender case along with the holster to fit their duty belt this is what you will need. Any of the heavy duty holsters from OB will work but this is what I ordered. http://www.amazon.com/OtterBox-Heav..._1_2?ie=UTF8&s=wireless&qid=1281806126&sr=8-2 You might could find it even cheaper on Ebay. You will then have to use a set of pliers to remove the inner portion of the clip. Be careful because the plastic might break. Here are some pics of holster with the new clip. It functions as new and everything. You can see how the clip is held on in the center. You will have to pry those together to pop the clip off. Photos taken with iP4 Enjoy!!
