First of all, thanks for a really nicely coded app, certainly helped to raise my phone bill
Ontopic:
The reverse lookup feature you have implemented, where does it retrieve its data from? Since I have been able to reverselookup a numer that the (local) reular lookup services wont resolve for me.
And what API have you used for this lookup? (if any was provided from the service providers)
Thanks in advance for the reply.
