i dropped $165 for a key when they had 3.0 it's now 4.0 an works on future versiona and the key can be swapped from one pin to another i use all the time @ work best money i ever spent
i think the reson why rim hasn't had MSoffice modifiers is caus that would force thm to sign a blanket contract with satansoft an jack the price of the phone up by $2-300. BAD idea. the day that happens is the day rim dumps BB OS for WinMO
