Owned? The 7230.
I had a work-issued 957 for a short time until we dropped the entire program in favor of simple cell phone communication. We went to using our own cell phones and submitting the bills for reimbursement.
We were a small Wall Street firm and did whatever our Managing Partner wanted to do. He was a total non-techie so you can imagine the ideas he came up with were a lot like what you'd get from Dilbert's boss. We were supposed to highlight each call that should be reimbursed, make a total on the bill, and hand it to one designated guy in the office. His job was to look our bills over, make sure we weren't submitting obvious personal calls, like to our home phones, and that our totals added up correctly. All this in addition to his regular job! We were all grumbling about having to screw with our bills every month, he was even grumpier that he had to double check our stuff, and nobody was in a good mood. We'd practically throw our bills at him with a curt "check THIS, dickwad", he'd answer back by flipping us the bird, and life went on. Then he quit. The rest of us flat out refused to become the designated checking douchebag so the program died a needed death. We just paid our own friggin' cell phone bills. Bear in mind that this was $30 to $40 per month for most of us, and we were making good coin on Wall Street. Totally idiotic idea from start to finish.
