1st review? I've been using this app for a couple of months now. I'm happy enough with it. It has fallen over and crashed a few times but that's probably due to my phone incompatibility rather than anything else? I especially like the reminder of available credit, once it associated and registered, very handy. There is nothing better than using the soft-phone to answer a landline call from the warmth of the bed!!
