I bought a Android phone (HTC Desire) a couple of weeks ago and I have never been so happy with a phone ever. Extensible etc. One thing I wanted is to check which operator a contact has so it will be simple determine how much it will cost to call them.. there was no such application so I started to write one inspired by the application KtoryOperator already on the Android Market. After a couple of days, writing, adapting and changing it’s ready. So if you have a swedish phone number in your contacts and wish to look it up just download the “Vilken Operator?” software from Android Market and you can check your phone book.. comments are appreciated and also bug reports (this is my first ever java-project).. send them by email!
