When JSONData is called on a NSDictionary that has a key value pair that has a string encoded with ASP.NET Date format (http://weblogs.asp.net/bleroy/archive/2008/01/18/dates-and-json.aspx) the backslash in the date format is incorrectly escaped with another backslash.

For example:

"/Date(1303502009425)/"

is encoded as:

"/Date(1303502009425)/"

This should not be the case because the JSON spec indicates that the forward slash can optionally be escaped.
