Help choosing a Hi-Fi/ Speaker System?

I need to buy a decent Hi-Fi/ Speaker system soon but I need it to have Bluetooth so I can use it with my iPhone, it also needs to have an input so I can plug my pc sound into it. Does anyone know one with these features on eBay (available to Australia) that doesn't cost too much. Not too loud 25 - 100 watts RMS is fine.

Also how do I link it up to my computer I.e. Do I need a sound card, what cables do I need? I'd rather not have to buy a sound card if possible, maybe I can just use the motherboard outputs?

Id rather that it was 2 speakers so I can put them each side of my tv with a small control box or something (if this even exists?)

Any advice is appreciated, thanks.

Why hasn't my iphone automatically hung up on a caller?

Why hasn't my iphone automatically hung up on a caller?

Added (1). I avoid answering unknown callers with my Iphone, and right now I have an inbound caller showing on my phone that I haven't answered. Only issue is that its showing this incoming call for the last 30 minutes! I.e. Its showing that I have a number dialing me and that I can 'slide to answer' for that long - the person whoever it is, hasn't hung up! Is that even possible?! My phone normally goes to voicemail, why hasn't it for this call?

My iPhone reset during iOS Update?

My iPhone reset during iOS Update?

Added (1). In the middle of an iOS update, my iPhone reset for reasons unknown. When it came to again, it was in recovery mode with the "connect to iTunes" symbol on the screen. Several resets later yielded the same result. I know I should restore and update my phone on iTunes, but the problem is I have lots of documents that haven't been backed up. Is there a way for me to restore my phone and update it via iTunes without losing everything as well?
