I hate my BlackBerry Storm. I want an iPhone!

I'm at my wits end with the ****** BlackBerry Storm 1! This is the worst lemon I've ever bought and RIM won't even talk to me without having to pay them tons of money without any guarantee of service! The ****** Storm has gone back to RIM for its 2nd OS install because once RIM's mac desktop manager trashes the phone, there is no way to reinstall the OS. Is this the same with the iPhone? Can a totally trashed OS in the iPhone still be reinstalled without having to send it in for repair? I've already had to reinstall the OS on the ****** Storm at least 2 dozen times in 7 months and my backup cell phone is now having issues after years of use so I have to buy the phone at full cost to avoid penalties of voiding the rotten Bell contract.

Am I going to have tons of problems with the iPhone, too?
What kind of extra warranty do I get with the iPhone?
