I had a personal AT&T account since the iPhone 1. I always just kept my personal phone for work use and turned in my bills for reimbursement. The problem was I always forgot to submit the bills so mostly ended up paying my bills by hand. So, when my personal iPhone 4 got stolen 3 weeks after i got it (1st day of launch) i talked to my IT department. They were able to port my number over and get me an iPhone. This was my only option as apple wanted $699 to replace my phone that i paid $299 for. My question is what happens if I leave my company and want to keep my personal number as well as have an iphone (preferably an i5 of course) or just go back out on my own plan. How do I figure out if I can do this and what it would cost? Or is it easier to jump ship and go Verizon?
