Years ago Apple revolutionary the Phone with the iPhone series. Indeed it was a phenomenon at that time! people are camping days, and week before the store start selling it, it was quickly become a hot grab and everyone eager for it.
Google fighting back with the Android OS, an open platform OS which had started a spark for a competitor for the iOS, lots of companies adapting it HTC, Samsung, Sony (formerly SonyEricsson).
Except for Nokia which was so 'ego' of their Symbian OS which had issue with the memory management rejecting the idea of adapting/incorporating the Android OS into their phone model. With the changes of the Nokia CEO with the MicroSoft Officer they are now goes to Windows Phone 7 OS which is not a popular OS for now.
So, ask yourself, did you see any Nokia phone around? Maybe for a second phone for the 'special one'? hehe i dont know but Nokia is plunged down, along with their Windows Phone 7 and MeeGo.
