I used iphone 4s for 2 months and then still having battery issues plus siri being no use, I decided to go with Samsung galaxy s2 white. My service providers (Three UK) really helpful and did do the swap for the phone without any issues.
Now having used the samung galaxy s2 for a few days, I can tell that ios 5 and siri are some features copied from andriod market and samsung s2.
The voice talk in samsung agalxy s2 works far far better in recognizing your voice and has never made a mistalke yet in understanding what i say, plus it doent haveing to go usrfing around the world like siri does when it says let me think.
And all the features and modification you can do with samsung widgets is great. Apple looks like its trying to copy andriod os, but its that successful.
1) Siri is a copy of samsung voice with some silly addded features
2) itunes wifi sync is a copy of kies which samsung launched, plus kies works better because u dont need to download a software for it, kies in samsung phone will give you a unique address to type based on the wifi network you are connected to, and just type this address on a browser, off you start uploading and downloading software to your phone and all songs.
3) Andriod market allows you to download apps on the market and apps will be downloaded directly to your phone.
4) Phone is safter thinner and better sized screen than Iphone 4s.
5) and you HSPA + (so called 4G)
So with this note I off the Apple forum for good.
Thank you
