I Have iPhone 4.should I get iPhone 5?

Should I get it in black or white and why? Would white get dirty easily or easily to tell it got dirt or something on it?
and also, the reason why I want iPhone 5 is because it also has Siri which is improved and better picture resoultion and has the HD look and iPhone 4 does not. Also, the 3D look on maps looks cool too.

Added (1). I know I can update it to iOS 6 but it sucks because it doesn't have Siri on it

Well its really your decision.
but if it was me, I would say no. Because you can just update your iphone to IOS6.

Don't get the iPhone 5, there aren't huge amounts of changes, just the a6 processor, better resolution (still retina display.), and it's.3 inches bigger than predecessor. Of you have that much money to spend, get a Samsung galaxy s3.It is far better than iphone5 in terms of resolution, processing power, features, battery life, expandable memory, interchangeable battery, bigger screen, etc

Yeah it's a pretty substantial upgrade. No it doesn't get dirty, I don't understand how/where that rumor stemmed from. I had my White iPhone 4 for a year and a half and it has yet to get dirty. From all the things you want you can definitely benefit from an upgrade to the 4s or the 5 but in my opinion you might as well get the 5 since you won't be able to upgrade for 2 more years.

First off, iOS 6 has Siri, it was a speculation that it wouldn't since the people who helped develop it also help develop their processors. Apple stopped making iPhone processors with them, but for now Siri stays.

Well Gizmodo is playing with it now and is constantly updating their article with what they think of it.

There's a video of all the features of the iOS 6 in 3 minutes.

Remember that a few iOS 6 features are iPhone 5 exclusive.

Well if you have the money and needs then go for it. Apple sure targeting people like you.

You don't really need the iPhone 5 just for Siri. But if you do get it, black is best because dirt shows up less. The 3d map only works in certain countries by the way.

I've got an iPhone 4 and I'm not planning on upgrading. Except the map app, iOS 6 runs great on it. I got Siri on my New iPad and she is overrated; not worth getting a new phone over.

Don't get an S3. The equivalent of a powerful but unreliable American car to an efficient and intelligent Japanese or European car. Resale is similar too.

No just no. Get the Samsung Galaxy S3. 4.8 inch screen with Quad core processor. Sum it up, the iPhone old now t.t.
