IPhone 3GS - Restored, No Sim

So I received an iPhone 3GS as a gift because my uncle didn't like the handset, my auntie said it was 'broken', i wasn't really sure what this meant as over the past couple of years I have used a very simple phone.

I was trying to update the iOS (?) so I could get the imdb app whilst on itunes, but then my iphone froze. I then clicked 'restore' on itunes as nothing I was doing would restart it.

Now when I turn it on it goes through the options of choosing a language, choosing a location then it asks me to connect to itunes or Wi-Fi.

When I try it through Itunes it says "There's no Sim card installed in the iphone you are attempting to activate" - yet there's a sim card in it and i have tried disconnecting and connecting several times like they suggest but there's no change.

When I try and connect though Wi-Fi it says "Your iPhone could not be activated because the activation server is temporarily unavailable"

I have read online that there's no way to fix your iPhone if it is in this state, but surely not! What a waste.

New radio for Volkswagen Beetle

I have recently gotten a 2001 vw beetle. Mechanically it is in great condition, but cosmetically… Just horrible. I'm wanting a new radio, but having all my music on my iPhone I would LOVE one with an aux port or USB. The only issue is that the space to fit a new radio is extremely skinny and oval. I know they make the spacer type thing to fit between the new radio and the hole, but I have not seen a radio that is skinny enough to fit.

If you have any help for me a would greatly appreciate it!
I also am looking into new speakers also since the ones now are blown. I would like something that hits hard and sounds good. Any suggestions are appreciated.

My Iphone 4 is taking ages to sync my notes, step 3?

My iphone 4 takes so long to sync notes which is step 3! It still has never gone pass step 3 because i have had to cancel it because i'm either going out or need to use it for something but i have left it for about 6 hours before and it just wasn't doing anything! I have deleted all of my photos and some films and tried again but no difference and there was about 755 photos on my iphone and about 3 hours worth of film. It doesn't allow me to put music or videos onto my iphone either. I really need to do that because i'm going on holiday soon and i don't want to be bored as it is a very long journey.

Syncing iPhone/Mac calendar?

I've already synced the calendar on my mac with my iphone but I was wondering if it already did or if there's any way to where if I were to add something to my calendar on my phone it would sync and automatically add that event to my mac?

New IPhone 4 lagging on games

I bought an iphone 4 three days ago and it worked perfectly fine with games until yesterday.
every time i would play a game like temple run or nazi zombies, there's like a millisecond lag every 4 seconds or so. I mean, this isn't i big deal but you would expect it to run smoothly for the price you pay. I even tried it with my dads and it works fine.
I have abbout 5gb of stuff on my phone which isn't too much.
However, whenever i put it into flight mode, the games work perfectly fine. Yesterday and today, i'm at my grans house where there's a very bad connection. You either have no signal or 1 bar. Could this have something to do with it? Because it started when i got here. Also, when i turn it off and back on, they would run fine but gradually start to lag more after time.
please help, because little things like this really piss me off!

Dropped iphone in toilet - 1

Hi, so yesterday morning before i went to school i dropped my iphone 4 in the toilet (yeah i know, super bad luck!) and i took it out immediately. It worked perfectly fine as i shaked some water out but yeah i just continued to use the phone as per normal for the whole day till the battery went out.

then i went online to check what i should do and it says to leave it in rice so i did exactly but i just wanna know how long i should leave it in the rice before i can charge it again?
