Devices with MSFP
By now, you should all already know that Exchange Server 2003 SP2 DirectPush is only available to devices with Windows Mobile 5.0 and with the Messaging and Security Feature Pack (MSFP), right?
OK, the problem is that MSFP can't just be downloaded and installed as a regular update, you must obtain it through your OEM vendor.
Jason Langridge compiled recently a list with the most recent devices with MSFP:
O2 XDA Mini S
Sprint PPC 6700
i-mate (updates via www.clubimate.com)
SP5 e SP5m
QTEK (updates via www.myqtek.com)
