Well, I have posted my question in last minutes but I could not find that one. I have to post a new one and add more details to my question:
I have tried to use other web services. All of them work fine, except the one I am using: http://ws.geonames.org/cities?. I do not know if this is because I have used it too often, which I really do not think so.
So is there someone could help me about it or give me some suggestion ?
Thanks a lot for your reply. I have another question here: could you tell me when it will be available ?
You know, tomorrow, I have to use it to give my supervisor a demo. So I just want to know if it is OK by my tomorrow noon(about 12 hours later). Thanks a lot.
