Spoke to my guy at TMo BB tier 2 support. He told me that the $20/month is for unlimited e-mail for international roaming, but the data is definitely going to run you $15 per MB. I have had months where I use my BB fairly heavily for internet access and don't really go WAY out of hand with the MBs. I too am going overseas to Amsterdam in the VERY near future for two weeks, and I was concerned about this as well. Got the unlock code from TMo. Going to search around to try and find a prepaid data SIM to use while I am there. I know they have them, I just have NO idea where to find them.
