I just launched "Blackberry Desktop SOFTWARE" - which must have been an update from RIM and REPLACED my Blackberry Desktop MANAGER which had an IP Modem option for tethering (I was a successful AT&T user who was able to change 'false' to 'true' and use my BB accordingly) I can no longer find the IP Modem option for tethering! DID RIM in fact change the Manager to Software and wipe out this option!!??
