UPDATED: The latest X firmware turns the X into an X 1/2, or sort of an X2. There are a lot of improved, changed and new features in this latest firmware.. Read on to see what's new or changed.
First of all, the changed features:
GPRS: The GPRS bug in the previous releases of this firmware has now been fixed.
Camera: The night mode is gone. The camera's response to lighting levels overall has been vastly improved.
Camcorder: Much faster frame rates are attainable.
MP3 player: Less pauses when switching between applications.
Messgaing: The SMS counter bug is *finally* fixed.
Contacts: The annoying "Copy SIM Contacts" message has gone.
Keylock: The annoying double press problem has been fixed when unlocking the keys.
Network: Network acquisition has been sped up quite a bit.
RAM: The phone now has over 5MB of RAM free on startup, a gaining of over 1MB on most phones.
RealPlayer: Users report that frame rates on video play back have increased tremendously.
Backup / Restore: Backups and restores now seem to happen faster. MP3 playlista are now restored (they never used to be) as are call logs!
New features, not previously seen on the Sendo X:
Speed Dial: You can now set applications as well as phone numbers as Speed Dial allocations.
Now!: Many new features, including the ability to toggle on or off the section headers. To do this, press and hold the left or right side key (the silver ones) - the one you need is the "Edit" key (i.e. not the one which activates VoiceSignal)
Easy Start: A very nice new way to automatically setup the MMS, WAP, GPRS and other settings for your phone. Much easier than even the Sendo Online Configurator.
