Well i agree with AZEEMMAJEED's suggestion
i was an apple fan but after switching to samsung androids phones i really started hating all apple products.
Evrytime u upgrade it u have to wait for like 2 months for proper (unthethered) jailbreak.
Can't play flash in browser..
No plug n play option. u always have to use itunes For transffering media etc
Small screen with fair screen resolution
In short, stick with ur s2 rather than switching to iphone. A good update will be only s3.. Its time to switch to quad core processor phones
