Same question for Instant Messaging applications such as MSN Messenger?
Very probably. MSN is closed source and will only run where Microsoft wants you to run it. But there are many Open Source IM clients, many of which have a plugin architecture and so support the use of more than one IM protocol, even simultaneously. One example is Pidgin, formerly called GAIM. GPRS does induce a certain amount of latency but that should not be a problem for simple, text-oriented chat between parties. And the GTA02’s WiFi will make it even better.
