New Android Market
There's a new market app floating around version 3.4.4. So far it looks identical to the previous editions that sport the tiles but it has definitely been given a huge speed increase. It's lightning fast, check it out.
To install in root explorer backup previous Vending.apk to something like Vending.apk.back
Copy new market to system/app and rename it to "Vending.apk" if it isn't already and set permissions to rw, r, r, and reboot
Edit, if you wanted to do it in ADB.
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
mv Vending.apk Vending.apk.bak (backs up old market just in case)
rename your file Vending.apk in Explorer
adb push Vending.apk /system/app/Vending.apk
chmod 644 Vending.apk
