IPhone 4 to 5, Worth the upgrade?

Since the iPhone 5 was just shown, I was wondering if you guys would think it's worth upgrading my iPhone 4 16GB ( I've had it for 2 and a bit years now) to an iPhone 5 16GB?
It doesn't seem to impress me that much, but do you think it's worth me spending another £529 on it?

Will the iPhone 5 tell you if your text message was delivered?

I'm not sure if other cellphone companies have it but Verizon shows a check mark if the text message is delivered to another Verizon user. I was wondering if anyone knew about it? Maybe not because it's not released 'till September 21st? I like to know if the person actually got my text.

Can gevey unlock a disabled iphone 4s?

My mom changed the password of her iphone 4s, forgot it, tried inputting password many times and the phone disabled.passcode entry is not allowed and only emergency call can be made. No syncs were made in itune

i can connect the phone to laptop, open itunes, hold power button and home button, release power button to get phone into recovery mode. After that i can press recover in itunes, however doing that will erase all the data on the phone and i don't want that

i learnt of gevey sim card from here:-

if i buy it and put it in the phone will it remove the disabled and unlock phone then allow for new passcode to be entered?

Iphone 3gs turns on and off repeatedly?

I charged my iphone all night and it didn't charge. I can't even restore the phone because it keeps turning on and off showing the apple logo for about 5 seconds and then turning off. It won't show up on itunes either. I tried to put it in dfl mode but i can't, as it interferes with the on and off twitching. What can i do?

Thank you

Can I charge my iPhone from the US in europe with just the plug changed?

So I live in Norway, and I'm considering buying an iPhone 5 from the US when it's released (as my brother lives there). The only problem is the charging. Can I use my US iPhone on the 230 V power net in Norway, by only changing the plug on the end of the charging cord, or do I have to carry my large converter box around if i wish to charge my iPhone at my friends house etc?

Why is th iPhone 5 is from $199 in America and from £529 in the UK?

It doesn't really make sense to me why the iPhone 5 is $199 in the US and £529 in the UK. I know that the values don't match when converted, so am i just being stupid or do the people at Apple think that everyone in the UK are too ignorant to see the difference in price.

Anyone know the answer?
