the other reason for insurance is sprint used to repair/replace manufacturers defects in store, now they are going to start to send you back to the manufacturer, except when you have insurance. For things like broken screens, damaged housing, broken ports, and other user damage in which the motherboard is still working, they will only charge you 35 dollars to repair it, instead of 100. This does not include water damage.
If your phone is lost or stolen, then you just pay 100 dollars to get it replaced. The question about insurance is simply this, do you think you would use it? If you think that in the next year you would use it, then by all means get it. For me, a phone is a tool. I dont baby them, I dont cuddle them, I dont care if they have a bad day. I really dont care if they look like they got hit by a truck after a year. For me, the insurance is worth it. Even though I could afford to get a new phone if the one I have broke, I really dont need anything more then the evo. So 184 dollars vs 400 dollars is just simple math. After you past the upgrade date, I usually drop the insurance, because if the phone breaks, you can just upgrade to another one.
I have use the insurance 6 times in the last 4 years. Total cost out of pocket for 6 phones, $1104 dollars. Total cost out of pocket if I did not have the insurance would be, $3194. For me, 2 grand is 2 grand. If you dont plan on using the insurance, then don't get it. Take the money, place it in a account for 2 years, by then you will have 300 bucks which will cover the next upgrade. I really don't see myself making it through a year with out using the insurance. Now before you guys start to jump down my throat, it really depends on where you live. In some states, if you intentionally break your phone they have to replace it, regardless of fault.
