My iPhone power button won't work, so I can't restart it. The problem is that I've several problems with my phone, the first was that it won't show the Album Artwork, so I tried fixing it, one thing led to another and now it can't play any 41 songs that I guess I was supposed to un-sync in the process.

How long does it take for an Verizon iPhone 4s to process & ship?

I ordered an iPhone 4s on April 30th, Wednesday. It's now Saturday, May 3rd. Verizon sent me a confirmation email saying that it is being processed & that I will receive notification when it's been shipped. I still haven't received an email saying it's been shipped. So I click the link in the email that says "check your order status" & when it takes me to the site, it says that it's so being processed. How long does it take to process? It was supposed to ship overnight. & no, I don't have a tracking number. They didn't give me one.

Is 4GB ram enough for what I want to do?

I'm buying a 13" MacBook Air for sixth form to do my work on. This means I will be using the laptop to do simple tasks such as writing documents, spreadsheets and powerpoints etc.
I will be doing a lot of web browsing and watching youtube videos and using google drive.
I would also use the laptop often to run iPhoto, rosetta stone and also to play Age of Empires 2.
If it makes any difference I will be using iTunes a lot as well to sync between my mac and iPhone.
Although a situation in which I would need to do all these things at the same time probably wouldn't arise, I would like it to be able to so, so there's always some 'buffer memory' if you like.

Will 4GB ram be enough for me? Or do I need to go for the 8GB ram option?
