[XPERIA X8 General] kecil26:
1.You can have flash in 2.2 and above ROM..but atm,i dont think theres is fully working

ROM yet to play with it..most of dev a trying their best to make completed ROM,so please be patient a bit.You can try Racht or Jarpelea ROM which is the best rite now for X8, search for it in X8 Android Developement Section.

2.Yes every phone is shipped with stock ROM and we need to rooted it to be able to customized it, Yes you can also turn your phone like HTC Desire or G1 or Samsung Galaxy but in what thing? if u said ROM,you'll have to wait for dev to port the ROM to our X8. and if u said about theme,theres alot of theme,app that can change ur X8 interface to htc,g1.

3.As an regular user, idont think u have to know what modules is,its related to system driver or kernel that u dont want to messed with.Sense is a theme that available on every HTC phone, what their mean by "X8 run on HTC sense" is there a able to use HTC Sense theme on our X8..have u ever see Sense clock? the square white flip clock that available on every HTC phone, thats one of it.

Firmware is also known as official things@app from SE like ROM and App.

2.0.1.a.0.47 << this is an old ROM, the latest one is 2.1.1.A.0.6..Yes u should have to update as every update mean better performance, and bug fix..u can update via PC Companion..updating will clear all your data in internal memory, so it doest matter if you already rooted,PC Companion will install new ROM and you have to rooted it again. Yes you are rite, most of dev customized their rom based on latest ROM@firmware available..Yes again,update will wipe all your things located in internal memory and be replaced with the new one, so upgrade through PC companion and rerooted again.

xRecovery is an app that able u to flash@instal modified system file,able to backup and restored your whole phone if something goes wrong,able to flash@install custom@modified ROM and many others,i can say it a must have app if u always want to messed with ROM @ custom file from dev.

JIT mean JUST IN TIME,its a file that able to boost your cpu and at the same time save you battery (for me) what is mean by Just In Time is,when u used this file,cpu will only be used when needed eg.opening app,playing games.

Floyo? Froyo? Gingerbread? <<<its a name of ROM,floyo is modified ROM name taken from Froyo which is official Adroid ROM..2.1 (Eclair),2.2 (Froyo),2.3 (Gingerbread)..we are 2.1 which is eclair.

Flashing Roms same a isntalling new rom,upgrading new rom,changing rom to ne one.used xrecovery to flash new rom.

SI number as i know is country code number that determined your location.let say:

2.1.1.A.0.6 for ORANGE <<<build number ORANGE is carrier

SI 1241-4645 <<<<Location code,we cant have same SI number as him if we are from diff location.

multitouch works on x8 <<<Not yet until dev able to crack@hacked@modified SE bootloader,multitouch need a driver that properly start whan device boot

(bootloader is SE app that check every driver on every boot,every driver have some sort of SE sign to determined the officiality of the file)

WHY some people can have their x8s running on android 2.2 or 2.3? WHen running on 2.2 2.3, what's the advantages.

==because dev already port the ROM to suitable with X8, that y they can have it running on our X8. 2.2 and 2.3 is a latest build,as you know latest build mean better performance,latest things added in the ROM,and flash can only be run on that ROM..thats the advantage!!

Yes,i think u should update your phone first.

Here you go,hope that i already answering all ur quest.
