jQuery's Mobile Testing Lab
Very close to a complete mobile testing lab for jQuery and jQuery UI. Need another WinMo phone and a few more iPhones and an iPad - but we're in good shape.
We're setting up the testing lab at Filament Group for easier testing and working with the Filament team. www.filamentgroup.com/
I bought all the phones from Gazelle: www.gazelle.com/ (except for the ones explicitly donated).
