I have recently experienced that my iPhone is not recognizing my sim card and as a resulting, only being able to do emergency calls and is unable to use my iPhone. Sometimes a restart resolves the problem. Also I believe that the iPhone is dropping connections to my EDGE/G3 network during use. Several times have been waiting several minutes for Mail and Safari to start receiving mail and load pages without luck. Furthermore YouTube is calming that there is no connection. Dont know if this is related to the connections issues Im having or it is isolated. Now am I the only on having these problems???
