Not sure if this makes any difference.
Anybody any ideas on cost?
You're sim card needs to be enabled on the BES tariff with T-mobile to enable a BES server/handheld to work. If you have only a BIS account it doesn't work. If you call up T-Mob they may be able to tell you the cost of the upgrade.
FWIW on O2/VF the RRP's are £12 for BIS and £36 per month for BES. I have no idea of the T-Mobile costs as we don't deal with them.
