Where can I find all the apps I've ever purchased on my iPhone 4?

I recently upgraded to an iPhone 5C and the guy at the Verizon store said I'd be able to access all the apps I had ever purchased through the App Store on my phone, but I've only been able to find a couple that way.

I rarely ever synched with my computer and I didn't have an iCloud option on my iPhone 4, so I doubt anything is backed up through iTunes or otherwise.

Where can I find my complete app purchase history, free apps included?

My RCA stereo receiver is frozen on the AM/FM function. How do I fix this?

About four months ago, I bought an RCA rt2870a stereo receiver off craigslist for $60. The unit worked perfectly until about a month ago when I decided to try the other functions. I hit the AM/FM button and ever since then, I have not been able to switch the unit back to any other setting. I have already tried contacting every possible customer service outlet possible for this device and they have all been inadequate. The unit is functional, as in it has the ability to turn on (not manually). I can't turn the unit off without unplugging it and then the only way to turn it back on is by plugging it back in and waiting for it to turn on by itself. The volume knob still works and will display the volume level but then will go back to displaying " PM 87.50". I don't have the FM antenna for it but still, there's no reason why it should be frozen like this. The only thing I use the unit for is listening to music from my iPhone, but now I can't because it won't switch from the radio function. Getting another unit is not an option right now.

Can I use my warranty for this?

I got an iPhone 5c in December 2013 and my warranty doesn't wear out until December 30 2014, my friend dropped my phone and it shattered. A few weeks later it's shutting off by itself and it takes a few tries to get it back on. Then it finally gives out and stops Turing on. Can I use my warranty to get a new one for something like this?

How to know if I got deleted on BBM (iPhone)?

I was talking to someone earlier, they read the message but didn't reply (we was a bit angry with eachother) then I said sent "Why did you blank the message" and it said this person doesn't have you as contact would you like to re-add. I know from previous experience when someone deletes you they'll be removed from your contact list as well, but their still there. I'm curious but can someone clarify?
Cheers
