@d3m0n - Viber for new platforms is being developed these days: Viber for Blackberry is coming soon, and even Viber for PC/Mac is being developed. In the future, we plan to expand to more and more platforms, like Symbian and WP7.
@CuriOu5 - thank you for the information and the screenshots. At first you said Viber will force close immediately after install it (so you couldn't use it at all). Has this changed now? How?
Also - about the new problem you described now, can you please try to elaborate on the exact steps by which we can recreate this bug? Start from the beginning, step-by-step, so we can test it here in our labs.
@ryuzaki_L - it's a standard feature of many apps (for example - WhatsApp) that imports your contacts from Android's main app, and uses them in order to find other friends of yours who already have Viber (or will install it in the future).
@hxcpride - About the galaxy-galaxy calls: make sure both of you are using high-speed WiFi networks, and if you are, try using a different WiFi connection (both of you) in order to isolate the problem.
About Wildfire: unfortunately you are right (and we explicitly wrote that in our website). Wildfire is not 100% supported, and due to obsolete technologies it uses, Viber calls may be disrupted on it
