The new Palm pre firmware 1.4 has been released.
However Rebel sim II is not Fully Compatiable with 1.4 firmware unless some firmware modifications is made but Rebel Simcard II is still the only way to unlock the Palm Pre phones.
Users who upgrade to the 1.4 WEBOS firmware will not be able to use the 3G UMTS networks. The 1.4 WEBOS firmware restricts the Rebel simcard II from being able to Generate Network Authentications keys due to the Modem Baseband software being updated by the 1.4 firmware.
