If you haven't already installed Cyanogen's ROM on your Android, we suggest doing so now. The tips and processes below expand on the speed boosts and data freedom already bestowed by the 'rooting' process, but require the root access and Cyanogen firmware too. It's not a painful command line process, and it took me only about 30 minutes to do so, while simultaneously keeping an eye on an over-eager puppy.
Moving your applications to your phone's SD card, referred to as "apps2sd" in geekier circles, is said to "free up memory," along with allowing for backups and increase the number of apps you can install—a limitation some heavy users have already hit on their lackluster G1s. Since we hadn't hit our limit of application installations on our G1, we didn't quite get why that would matter when we wrote our original feature. So we asked the Cyanogen developer if we'd get more space for app installations or actual performance, and he replied:
In other words, rooting allows you to tell your phone that, yes, it's okay to rely on the SD card to find applications and store your app engine's cached material, so go ahead and use much more of your internal memory for email, contact lists, image thumbnails, and whatever else you need. If you're a G1 owner still using your pre-installed 1GB SD card, now is the time to upgrade to get more space, as even 8GB micro-SD cards are seriously cheap these days.
If you're eager to get even more performance from your phone, and make it easier to keep up with the latest custom ROM advancements, here's how to get there.
Partition your SD card
If you've got Cyanogen's custom ROM installed on your (U.S.) G1 or myTouch 3G, it will automatically move your apps and cache space to any SD card it finds with Linux-formatted space on it. Your SD card likely arrived pre-formatted to the FAT 32 system, so we'll need a partition tool to rewrite it.
Before we forge ahead, connect your phone by USB cable to your computer, turn on USB mounting on the phone, and back up the contents of its SD card to a folder on your computer's hard drive. It's not necessary if you don't care about any of the pictures, music, or app data from your phone, but it's probably a good idea in case you forget about something.
There are a lot of partition tools that can get this re-formatting job done, but unless you're already running Linux with GParted installed, we recommend the GParted Live CD. It runs on nearly any system, doesn't require installation, and explains what it's doing to your disks in a simple way. Download a disk image, burn it to a CD, put it in your CD/DVD drive, and reboot your system. Hit enter to get through any boot screens, and when you arrive at the minimalist GParted desktop, plug in your phone again, but don't turn on USB mounting this time. Since you've backed up all your data from the big FAT 32 space, go ahead and tell GParted to delete it. Click the upper-right drive icon in GParted to select the drive that matches your SD card's size (likely /dev/sdb), right-click on the single partition entry and hit 'Unmount,' then right-click again and select 'Delete.'
Keep your custom ROM up to date
The folks behind the Cyanogen ROMs update their work constantly, adding new features pulled in from Google's Donut (1.6) build, fixing bugs and annoyances (both their own and Google's), and optimizing wherever possible. The way you first installed a custom ROM involves downloading a ZIP on a computer, transferring it to your SD card, wiping all your data, then manually booting into a "recovery" screen and applying the update—not impossible, but not something you'd want to pull off every two days.
nandroid v2.2 backup option. Click it, and your phone's firmware contents will be backed up onto your SD card, easily restored from the restore latest backup option if you ever end up with a phone that won't boot to your Android home screen.
We are, as you can tell, enthusiastic Android firmware tweakers, so we'd love to hear what you've done with your phone in the comments.

Windows 7 RTM이 출시되자 마자 업무용 노트북(WIndows 7 Profesonal)과 집에 있는 PC에(Windows 7 Home Premium) 모두 설치하면서 느낀점은 우선 빨라졌다는 것(엄청난 속도 향상은 아니지만)과 향상된 드라이버 지원기능이었습니다. 특히 집에 PC에 있는 HDTV 수신카드를 인식하고 드라이버를 설치 바로 Windows Media Center에서 TV를 보는 것은 감동이었습니다. 더욱이 Windows 7부터는 케이블신호도 인식합니다. (제가 잘 몰라서 그랬는지 몰라도 Vista에서는 공중파만..) 암튼, 개선된 성능과 드라이버 지원에 감탄하느라 본질적인 개선 사항에 대해서 관심을 가지지 못했습니다. 그래서 이것저것 살펴보니 재미난(?) 기능이 추가되었더군요. 우선,"
