Hi All, Question: I'm going to be sending my 3g iphone in to be replaced (sleep wake button broke) and wondering if I can just use my original iphone for the few days it takes? I tried to switch the sim cards a few weeks ago and it wanted me to activate and setup as a new phone and pick my plan and everything. Any advice on what I'm supposed to do from here? Should it just work when I switch the sims or do I have to set the 2g up as a new phone? Thanks in advance!
