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.
You can use this Tool Free if you have a rebel simcard II and can downgrade the Baseband of the 1.4/1.4.1 Palm Pre Web OS and then have full 3G and network renewal functions enabled once again like it was on the 1.3.5 firmware.
