Hi I've been trying to get to CS but doesn't look like I will with the high volume. I bought a Verizon iPhone (full price) and will be picking it up at the apple store. My plan is to just take out the verizon sim and put my att sim in. Reason I'm asking is b/c I used a friends account to order the verizon phone on his account. Will I run into any problems here? Will the store employee activate the phone at the store before handing it to me? Or am I good enough to take it home to get it working on my att sim?
