A few days ago, a new application I've created called Caller ID was released in Nokia Store. It's a handy application that gives you an opportunity to find out who calls you from any number not stored in your address book. You can either use the application to manually resolve identities behind any phone number or you can enable automatic resolution of unknown callers, which attempts to resolve the identity before you even answer the call. Usually resolving a number takes somewhere between 5 and 60 seconds depending on your carrier and selected service provider.
Caller ID uses public SMS services to find out the identity of the caller. These services are not provided by me and are unfortunately not free to use (since the application uses regular short messaging service, the costs are applied in you next carrier bill just as if you had manually sent the SMS to the service).
Currently Caller ID is only available in Finland because I don't know any foreign services working the same way as Finnish ones do. If you know a similar service in your country, please let me know and I'll add it to the application. Thanks!
