NO! It doesn't matter how much you paid.. It's what it would cost to replace! Call your agent back (you probably spoke to the new secretary anyway).

I'll give you an example and have it make sense.. You have a buddy who sells you jewelry for wholesale cost. He sells you an engagement ring for 10 grand. However, you get an official appraisal and it's worth 15 grand on the regular market. How much insurance should you put on it? 15 GRAND! State Farm needs to insure it for what it'd cost them to replace it. They can't get you those discounts again..

They have to insure it for $449 because that's the manufacturers price! And since that's over $400, it's insurable there at the cost I told you. Call back, tell them the phone is valued at $449 and you have paperwork documenting that (just print off the t-mobile's blackberry 8320 webpage).. As well as a purchase receipt.

You'll be done in 20 minutes, and if you pay with credit card over the phone, you don't even have to go into the office.
