Why can't itunes start a backup session with my iphone?

When i hook up my iphone via USB, itunes automatically does a sync and backup but recently i've gotten the notification that itunes can't backup my iphone because a session can't be started. Also, my ios 7 beta 1 just expired so currently, i can't get in to my phone- long story short, is there any way to fix this back up problem without having to change anything on my phone? Also I've read that it helps if you uncheck 'sync over wi-fi' on itunes; i did this and it didn't help.

Added (1). I want to backup so that i can downgrade back to ios 6.4.1. Do i still need to get a registered UDID?

Can I tune my electric bass using my iPhones headphone jack?

Does anyone know how to use your iPhone as a tuner using the headphone jack (since it receives audio too I'm assuming it can)? I'm not looking to use the mic because where I'll be tuning is too loud. Right now I have a reducer that goes from 1/4" to standard headphone, I think 1/8th". But its either the app I'm using, or additional hardware needed, it doesn't seem to be registering sound.

I bought a new iPhone 4 front screen through eBay because mine was broke. I fitted it, but after 3 months it's now not turning on. The eBay shop I bought it from said they all came with one year warranty

I've been trying to contact them the past few days but they're refusing to reply to my emails/ebay messages (despite leaving feedback for other users since)

Should this be pursued through PayPal?

Free iPhone Mirroring To Pc Software?

Okay, so i've heard of software like AirParrot, Reflector, Airserver but you only get trials of each of these programs. I was wondering if there was any FREEWARE I can download for my computer that simply allows mirroring. I don't need anything fancy like a rim around the projected image, hell, I don't even need sound. I just need a FREE wireless program that allows me to mirror the screen of my iPhone 5 to my Windows Pc.
