The thing with Apple is the replacement will have a warranty. Basically, it will be like a new phone again and continue where the original phone left off. If you had it for 2 months, you'll have 10 months left unless you purchase AppleCare. With a third party, you risk voiding the Apple warranty altogether, esp. now that you called Apple and they have a case regarding this issue. I can't say what to do for you, but sometimes the $299 is less of a hassle in the long run.
