Since I want to develop for ICS I would like to buy a 4.0.3 smartphone for testing my applications. I don't want to release apps I only tested with emulators (I guess who's ever developed j2me apps knows why...).
I have to choose between the S2 and the Nexus i9250. S2 seems to be more powerful and it is very popular but it is not the original ICS 4.0.3 style. Nexus i9250 OS is pure android ICS, also it is a bit cheaper.
Do android applications look different on the S2? Im talking about widgets like TimePickers and so on.
Sincerly, Wolfen
EDIT:
The main question is: Will TouchWiz affect my applications in any way?
Yes, they will.
Touchwiz and HTC Sense change the look of widgets such as buttons, date and time pickers etc. Starting from Ice Cream Sandwich, you can force the device to use the stock Android Holo theme look. But remember that Galaxy S2 comes with Gingerbread unless you update it.
