Hi,
Now that you have got a rooted Xperia X8, installed xRecovey, JIT and Link2SD, Live Wallpapers and everything is working fine...
What's next? Playing games, using widgets and apps?
SONY Ericsson has officially stop developing Android OS for the Xpedia X8.
Eclair 2.1.1. is the last software update.
Wondered what it would be like to run Gingerbread 2.3.3 on your Xpedia X8?
I have been using a "ported" new ROM called
Srom-2.3.3GingerbreadX8-V2 by stelios97 & zousoum96@ XDA.
The Quadrant score for this ROM on my Xperia X8 hit the roof -> 1000+
Xpedia X8 running Android 2.1 - Quadrant Score = 440
Xpedia X8 running Android 2.1 with JIT - Quadrant Score = 550
This "Gingerbread" Android ROM 2.3.3 is stable.

Crash/Rebooting Issues:a) Battery Drain Issues:Charge battery to 100%... and then some

<Reboot> into <xRecovery>
go to <Advanced settings><clear battery stats>
Note: New Li-Ion battery do not have memory effect so do not need to drain flat [0%] before resetting battery stats. In fact it is more detrimental to use a phone until the battery is flat.
Li-Ion batteries have approx. 500 charge/discharge cycles - after 500 charge/discharge cycles your batt is dead no matter what you do.
A partial charge/discharge reduces stress and prolongs battery life. So it's much better to discharge and charge your phone intermittently to prolong battery life.
b) Rebooting after installing applications --> New Root Explorer v2.14.2Root Explorer has been updated to <
Root Explorer v2.14.2>
I have been using this version for awhile now - seems to work better.
Still I recommend to...
use <File Manager> when you are installing apps
go to <settings><manage applications> to uninstall apps
Also note... "older" apps may crash because it is not updated to support Gingerbread 2.3 - so if an app you are using crashes/causes phone to reboot - simply install another similar "newer" app.
c) Rebooting after moving apps to SD Card:SD Cards should have only one partition [FAT32] and formatted with Xperia X8 [just to be safe

]
If you use a third party app to partition and format - do NOT name the SD card partition.
For Link2SD/APPS2SD functions
go to <settings><CyanogenMod settings><Application> select <Allow application moving>
go to <settings><CyanogenMod settings><Application><Install location><automatic>
Now you can move apps you have installed previously to your SD card.
go to <Settings><Manage applications><Move to SD Card>
Note: there will be apps that require installation in phone's memory (i.e. cannot be move to SD Card or app crash/reboot after you have move it to SD card). Check the developer's apps details for more information (usually says app supports APPS2SD). This is a app programming inherent issue.
d) VideoPlayer usage causing reboot:go to <SD Card> created directory <media> & in <media> folder create a <video> folder and put all your format compatible video files in there.
OR use... multi-format video players
MoboPlayer (supports multi-formats & free in Android Market) This app is stable and silky smooth when rendering of HD videos.
So far so good guys! I will keep updating this post until something better comes up.
cheers
