Harald -
Thanks for the list. We'll try to find one of these. I have a few iPhones sitting in
front of me, but unfortunately they are all 850/1900 and my available hardware is 900. :(
Does you have an example GSMTAP/PCAP trace of a successful PDP context activation using
OmsoSGSN? That would be useful for comparison. (And do you find the GPRS L3 & SNDCP
decoding in the current Wireshark 1.7 to be reliable?)

are having trouble getting our GPRS modem to recognize a ACTIVATE PDP
CONTEXT ACK message and are trying to determine if the error is in the
modem, in OmsoSGSN or somewhere in between.
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.
Better yet, is there anything out there that can
generate an L2 or L3
trace, like the Nokia 3310, but for GPRS as well as GSM?
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.

Harald
