I just got my first Treo and made my first international trip with it last week. Luckily, it worked on the ground in Thailand. But upon returning to the US, it crashed. There were three of us in our party with Treos, and all 3 crashed upon re-entry into the US. The result was that the software needed to be reloaded--SIM cards were fine.

Anyone else ever run into this problem when traveling with a Treo and if so, what countries?
