I've successfully used at least SE K800i, Google Nexus S, Dell Streak,
HTC Hermes II, Motorola A780 here on my side. I know some other people
have been using OsmoSGSN/OpenGGSN for iPhone related work, though I
don't know which particular model they've used.

The only ones that come to my mind are the TEMS variants of the K800i,
but those are of course hard to come by and/or expensive :/
Have you considered using Luca's work on gprsdecode? This way you could
do an air interface trace of what's happening between BTS and MS.
Regards,
Harald
