are iphones worth it?

I'm thinking bout getting a iPhone 4.0 I heard they fixed everything now so no moar errors. I can't go on contract cause of my age but I feel that buying handset is better in the long run.

If you go on contract you end paying upto £2000 including shit data charges.
I've got free wifi data sim from o2 currently in my 3Gs so I'd just use that.

 

LOL they still have a massive problem with the connectivity of the Iphone 4G but they are giving out some kind of case for your phone that seem to fix it.

But why buy a Iphone 4G when there are better options out there for less money?
But hey it's your money >_<
