With my Verizon contract running out first few days of August I plan on making my first step into the Apple world and purchase a 8 GB iPhone. My g/f and I are going to be in Chicago beginning of august for a concert and I plan on purchasing my iPhone at the Michigan Ave. Apple Store. My question is can I activate it on any computer since I will be away from home. Could I use a library computer or the business center in our hotel or does it become tied to the computer you activate it with. Thanks for any info.
