Mobile Handsets available for each OS.

Hi :
Having chosen which OS to go with.
If still unsure.
Maybe a list of available handsets will help.

Handsets for IOS (iPhone):
Simple this one.
iPhone 3GS (8,16, or 32 GB), iPhone 4 (16 or 32GB).

For RIM (BlackBerry):
Equally straight forward.
Bold 9780, Pearl 3G 9105, Torch 9800.

For Symbian.
Nokia C3, Nokia C7, Nokia N8, Sony Ericsson Vivaz Pro U8i.

For Android.
Dell Streak, HTC Wildfire, LG Optimus GT540, Samsung Galaxy S, Sony Ericsson Experia X10.

For Windows phone 7.
HTC HD 7, HTC Mozart, LG Optimus 7, Samsung Omnia 7.

The above are just a selection (apart from the iPhone/BlackBerry).
May only be available in the UK.

Thanks zebadee!
