We recently bought several iPhones 4 for our company employees in order to show how much we value them (this is true, guys!).
However, after using the new phones for a while we encountered a problem that some of them could not see the sim-card installed in them. The thing is that the SIM cards used by the new iPhones are smaller than those used in previous models. The new format is called “micro-sim” and the SIM cards seem to be at least one third smaller than the normal sims. Micro-sims look like this:

Unfortunately, to our great disappointment, at least two of the 5 iPhones we bought encountered the following problem:
We tried searching on the Internet for a solution but couldn’t find one and decided to dig into the problem ourselves (I`m sure our technicians were quite happy to do something not related to servers…).
What we discovered was what seemed to be a design problem of the mechanism ejecting the sim card tray in the new iPhones.
On the following picture you can see that when you insert a needle or a paper-clip into the tiny hole on the right, the sim card tray pops-out due to the pressure coming from the top part of the mechanism.
The problem is that the top part of the mechanism seems to have a design flaw and sometimes it touches the metal contacts on the sim card making a short circuit. As a result, the phone stops recognizing the sim.
When we found what the problem was we knew how to solve it. So here is the solution.
1.First, take some thick double sided adhesive tape and cut a small piece of it.
2. Second, stick that small piece of tape to the side of the sim tray as shown on the picture below.
3. Not put the sim card into tray and insert the tray back into the phone. Now the tape will prevent the top part of the ejecting mechanism from making a short circuit with the sim card.
So far we have been using our iPhones without a problem but it would be better if Apple recongized the problem and improved the design of the tray mechanism.
Please also note – we take no responsibilty for broken iphones whatsoever. Good luck!
P.S. One of our readers suggested another way of overcoming the problem. His solution is to put some tape on top of the SIM card as shown on the picture below. This should also prevent the short circuits but we have not tested this solution yet.
P.P.S. We still have some “special deal” servers for $20 in stock. If you are interested, do check them out!
