Is there much difference between iphone 4 and latest iphone?

I have Samsung galaxy ace which costs £22.99 a month this includes all round data i'm due upgrade and seen I can get iphone 4 for £22 per month this includes 500mb data. So need to know if iphone 4 is any good.

4 is good but obviously the latest version is way better.

Let me word it this way and you decide if it is OR NOT!

The IP4 is months away from being discontinued on release of the IP5S. Apple only support LAST 3 iPhones, discontinued means no longer sold by Apple, any future upgrades are for supported phones some new apps just WON'T WORK

On 12/09/2012 IP5 announced IP 3GS DROPPED, like the year before IP4S IN, IP3G OUT. No maths IP5S IN…

It may be the cheapest when compared to other iPhones but to invest any money in an OVERPRICED device is a waste as in 2 years you will be using a 5 year old device that came out in 2010. Many have already upgraded from the IP4 in 2012

There are newer phones better phones and they cost a lot less, giving you more than the 8Gb on the IP4, you should look at eg Sam Gal ACE II or the Lumia 620 for phone with a secondary camera microSD expansion Wi-Fi, GPS, DUAL CORE… AND BLUETOOTH MEDIA TRANSFER (Sharing) which no iPhone even the IP5 has. Here are the specs only if these phones are Gold Plated will it come in above the IP4 http://www.gsmarena.com/...hone2=5147

If you really want to step up and get the BEST Dual Core phone made by Samsung until the S 4mini comes along…
I really really recommend this phone (sorry about the choice of colour ) but this phone has 9 more features that the iPhone5 so even polka dot get it!
Here is my pitch (the phone on the left, phone on the right shows just how good it is the Dual core version of the Quad Core) http://www.gsmarena.com/...hone2=4238

Here is the phone & tariff http://phone-shop.tesco.com/pay-monthly-phones/pay-monthly-phones-listing.aspx?manufacturer=Samsung&model=Galaxy%20S%20II&networkProvider=&contractLength=0&price=0&colour=&group=&ratingScore=0

Yes the 5 is very different from the 4

The 4 is a good phone though, owned one before I jumped to the 5, but if you have the chance to get a 5, get that.

Make note though that both will get iOS 7 when it debuts later this year.
