We found that many users who had purchased a Rebel Simcard II for Palm Pre phones have had to loose 3G functions due to Auto software updates from Palm like the 1.4.1  which restricts usage to 2G only.

As this is not due the Fault of the Rebel simcard II Palm Pre users as updates can happen without thier knowledge automatically.
