Solution for Link2SD to work:

http://www.htcmania.com/showthread.php?p=2692474

1. Install “Script Manager” from Android Market

2. Open the Link2sd and when ask for the partitions and others will tell you that you reboot, after restarting do not open Link2sd

3. Open Script Manager

4. Go to: menu > more > advanced options > config > select “browse as root”

5. Give Superuser permits.

6. Click in the file /system/etc/install-recovery.sh

7. Select "run as root", "run at boot"

8. Save and restart your phone

9. After the restart you can use Link2sd

After all this, you can use Link2sd without doing anything extra

There is an important thing. When you reboot your phone (turn off and on) you will realize that all the applications that make link has disappeared from your home screens, app drawer, list of installed apps, etc. as if they were not installed, but do not worry. Open Link2sd and press the menu > more > quickreboot and all the missing applications will be available.

And voila, you'll have gingerbread working with link2SD..... :p

Rooted fit

install Busybox from market Busybox installer

Patience

Process:

1-Unzip xUltimate v2.2, and launch "Main.exe

2-If everything goes well xUlt should recognize the phone and make a connection. You now should see a list of options.

3-Run option 1. After option 1 is done, run option 2.

4-Now these well take a while. Run option 3.

5-IMPORTANT: After you have run option 3, you MUST navigate to the xUltimate folder and find "origi_frame" folder, and delete "guava.odex". It's a bad file, and interferes with deodexing process.

6-Now run option 4, and wait.

7-Exit xUltimate, and put the phone in USB mass storage

8-Go back into the xUltimate folder and copy "done_frame", and "done_app", and move them to the root of the sdcard

9-Go back into the xUltimate folder and copy "done_frame", and "done_app", and move them to the root of the sdcard

adb shell

su

stop

mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system

busybox cp /sdcard/done_app/* /system/app/

busybox cp /sdcard/done_frame/* /system/framework/

rm /system/app/*.odex

rm /system/framework/*.odex

mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system

reboot

Make sure that files are copied before passing to the remove step or you'll have to reflash your Rom

Your phone should now be deodexed!

You may notice an increase in speed, and you now have the ability to edit certain files with greater effects. (i.e. services.jar)

Next step: CUSTOM ROM but that is another story.
