I have recently purchased the Inspire 4g (should be delivered today) so I can unlock it and take it with me when I move to Chile. Should the SIM unlock be the only thing I need to use all the services on the phone? Will I have to change any settings to use text or data services. They have HSPA+ (call it 3.5G). Does the SIM card control this? I am pretty sure I will have to root to get the wifi hotspot, but does anyone know of any other issues I may run into?
