Which one should I choose ? (no budget)
- Apple iPhone 4S
- Sony Xperia S
- HTC One X
- Samsung Galaxy S3 (wait it launch soon)

My Priority is:-
1) Best in BATTERY LIFE!
2) SMS & Calender with appointments user-friendliness [use lots of this]
3) Camera Quality [better lens type, hope to replace my normal compact camera]
4) GPS

Thanks.
