FYI, Atom is not by HTC. It is quite obvious in the design and
styling of the device. The successor to O2 mini is Dopod 818. For
some reason, O2 decided to go with the other ODM.
A little out of touch, can't remember the ODM/OEM taiwanese company
and all of HTC's product name. Surf on the web and check out modaco
would provide alot more information.
Personally, I wanted the Dopod 818, but still deciding. Dun really
need it at this point, XphoneII works fine for my purposes
currently. Chucked the mini to GF.
EDIT: This website useful http://wiki.xda-developers.com/
and that other Taiwanese ODM is Quanta. Newer, and products overall
not so proven. Must have sold their Atom at a very good rate to O2
to convince them to use their device.
