OFFICIAL ÉCLAIR UPDATE:
Please note that Acer does not send OTA (your carrier might, but if you are currently on Donut, please follow this process). I believe this must be done on a Windows computer.
Go to Settings-->About Phone-->Device Information and read what it says in Product SKU.
It should give you some value which is either AAP-XXXX or EMEA-XXXX (AAP stands for Asia/Asia Pacific and EMEA stands for Europe/Middle East/Africa. The second part of the SKU goes by region. You must download the appropriate update package for your phone in order for the upgrade program to work).
Go to this site-
Acer Liquid 2.1 Official ROMs and download the upgrade package for your device. Follow the instructions in the PDF and voila.
While that is the best way to go about updating to Éclair, there is another way (this way also requires Windows). Note that for this way, you can flash any Acer Éclair version (eg. EMEA ROM on an AAP phone). Credits to Malez for this guide:
1) Make sure you have Acer Liquid drivers installed
2) Download the Acer Liquid A1 Download Tool-

3) Find a .bin file to flash onto your phone. I would recommend
2.100.07EMEA.GEN1 as it has the highest baseband version A1-04.04.05 or
1.100.71AAP.CSL which has baseband version A1-04.04.02 (NOTE: AAP ROMs only have English and two Asian languages while EMEA ROMs have English and many European languages. Also if you do plan on rooting, some people have reported problems with 2.100.07EMEA and adb remount when rooting stock ROM. I have tried two custom ROMs on this bin and have had zero problems.).
4) Unpack the Acer A1 Download Tool. And run the Acer Download Tool (IMPORTANT: For Windows 7/Windows Vista, make sure to right click it and Run As Administrator).
5) Click Browse and select the .bin file you downloaded. You might get an MD5 error, ignore that and flash the ROM. It will start flashing the ROM.
--If something happens, the phone can be unplugged (though it says it cannot) BUT DO NOT TURN OFF THE DEVICE.
COMMON BUGS:
The only bug I know of (which has only been reported on some phones running Éclair/FroYo) is one which causes your phone to freeze up while in standby if switching between 2G/3G/WiFi. The workaround for this bug is to force 2G only or 3G only on your phone (depending on whether or not you get 3G coverage in your area). You can do this by accessing the Testing Menu (dial *#*#4636#*#* in the dialer) and clicking on Phone Information. You can make a shortcut on your homescreen to this menu using AnyCut/BetterCut or by downloading TestingShortcut from the market.
If you know of any more, please feel free to post it on this board.
TIPS & TRICKS:
Task Killers (Credits to Vmanisme, I have come to the same conclusion):
--Because of the way Linux systems work it is not recommended to use any task killer, memory freeing tools, things like that. I tested this myself the phone does run better and gets better battery life without task killers.
Custom Wallpapers:
Make sure the size is 960x800. To set it as wallpaper (assuming you have Éclair), place the image somewhere on your SD Card. Go to your homescreen:
Menu Button-->Wallpaper-->Gallery. Select the image and use multitouch to crop the entire image.
Tethering:
WIRED TETHERING: One great thing about the Acer Liquid is that no external apps are required for wired tethering, it is built right into the device (no rooting required, works on all Éclair custom ROMs, does not work on any FroYo custom ROMs)! (credits to navygino on MoDaCo for figuring everything out):
1) Download & install this program,
Acer EasyLink
(I did this on Vista) Device Manager-->Modem-->Acer Android Modem-->Advanced-->enter the sting: +CGDCONT=1,”IP”,”apn name”
2) Open the Acer EasyLink software
3) Go to Settings
-The number is just *99#
-Make sure everything else is correct
WIRELESS TETHERING (credits to gengaro86):
Your phone MUST be rooted and MUST have a netfilter-enabled custom kernel installed.
AFAIK, these are available with most custom ROMs (does not work with Cyanogenmod6) as of right now and I do not think that any custom kernels for stock ROMs are available.
Once you have this, the app Liquid Tether must be installed, you can find it here-
liquid-tether - Project Hosting on Google Code . If you need any help, you can visit his thread on the MoDaCo Liquid forums-

ADB:
What is ADB? ( Credits to this Android Wiki )
ADB (Android Debug Bridge) is a tool that comes with the Android SDK that allows you to control and interface with your Android device.
