Updating an unlocked iPhone 4 on 4.3.3 to iOS 6?

I have an iPhone 4 on 4.3.3 version, firmware 04.10.01. My phone is unlocked via Gevey sim and I have no idea how to go about updating my phone to iOS 6. Will I still be able to unlock my iPhone via the same Gevey sim that was used to unlock my iPhone at 4.3.3? If not, is there an unlock for iOS 6 phones? And can I do this with my macbook?

IPhone not staying connected to iTunes?

Basically whenever I plug my phone into the computer via USB to sync my iphone, it will recognise that it's there and do the charging sign for about 2 seconds before just disconnecting and going back to my home screen. I don't think it's the wire because I have tried a different wire as well and had the same problem. Anyone ever had this?

Is there an ihome for the iphone 5?

I really want to buy an ihome, but i can't find one that is compatible with my iphone 5. I don't want to buy one and put an adapter on it because i read that it could break the phone or the cord. I want one that is specifically made for it. Are there any out there that i just haven't found yet?

Forward imessages from iphone to email

Does anyone know how to forward messages that are all from one person from your iphone to your email or PC? I just would like to read over every single conversation that I have had with this person since I bought the phone. I know that you can check each individual message one at a time, but I was wondering if there's a quicker way to do this because I have had the phone for about a year and have a lot of messages to forward.

Putting music on iPhone 5

So i just got the iPhone 5 today and my question is how do I put my music and apps on it? Is there a way i can do it from my iPhone rather than plugging it into my laptop? I have the 32g if that makes any difference.

When you load an mp3 to iTunes, do you still need the original file?

I download my music through other music downloading sites/stores and I only use iTunes to organize them and get the music to my iPhone. When I download these mp3's they are stored in my iMac's Downloads folder and I have a ton of music in that file. Do I still need these mp3's or can I delete the ones just floating around in my Downloads folder?
