Answer 1

This is something where iPhone tools written by the jail break community could actually come in handy to self-fix your phone's issues.  The primary thing to realize though is that Apple may be able to help with the problem themselves.
I don't personally jail break anymore, as I have no need to now, but I have experience with some of the tools out there.  If you are having this issue and your phone was jail broken, then you might want to deal with it yourself rather than taking it to Apple.  In many cases, it's totally solvable without too much trouble, and most likely you keep everything on it too.  Before I go into details on that solution, let me exhaust the Apple support logic.
If your phone isn't jail broken, then Apple is going to be more cooperative in helping resolve this.  If it isn't under warranty anymore, then that is a possible coin-toss.  If it's not under warranty, but you purchased AppleCare+, then you might have a real good chance.  Either way, you might just take it into an Apple store (you can make a reservation ahead of time), then explain the problem to them and see what they do.  If it is under warranty and not jail broken, then they're absolutely going to find a way to make it right for you.
So the final logic boils down to whether you don't have it under warranty and Apple won't help, or you have jail broken it, or you just feel brave and want to try fixing it on your own.  I'm not sure if I can mention specific tools here on the forum or not, but you should be able to easily google the tools which have Exit recovery, and Fix recovery as actions you can perform to try to fix the phone.  Both of these may require that you know how to put your phone into DFU (device firmware update) mode, which is another thing you can easily search for.  The tool I'm talking about may have a name that refers to a collapsible portable covering used in rain that may or may not happen to be some form of very small.  I think one should be able to catch the reference here without me totally naming that tool.
I have used said tool myself in the past and it worked great on several occasions where my previous phones acted up.  Having said that, I think Apple would appreciate me reminding you that they do not condone the use of such programs or tools which they have not authorized.
Good luck!
