I have been looking for something like this for a while. The flipout lacks internal memory and it soon becomes a problem if you want to have a good set of apps.

Here's what you'll need:

1. Rooted Flipout (I won't post instructions to this step, look for "Universal AndRoot")

2. Partitioned SD card (see below for instructions), depending on the method, you might need a phone with CWM to do this and ADB installed on your PC.

3. Download Link2SD from Market

So here are the steps:

1. Partition your SD card. There are many ways to do it. I will post two ways:
  • Use MiniTool Partition Wizard Home Edition

    My PC didn't like this tool and I wasn't able to use it. However, it should be quite easy, you just need to put your card in a card reader and build two partitions with the following characteristic:

    First partition will be your main card partition, should be of the whole card size minus the extended partition you want to create
    Second partition should also be fat32 (link2sd didn't like ext2 nor ext3 on the flipout, it only worked with fat32)
  • Use CWM. I personally didn't want to install it on the Flipout, so I used a Samsung Epic 4G for the steps. You should be able to use any phone with CWM to do it, put your SD card in the phone with CWM and boot into recovery:

    adb shell reboot recovery
    parted /dev/block/mmcblk0 (open partition manager for SD card)
    print (prints partition table)

    Here you should have one partition table, starting at some point and ending at some point like 7969 if your card has 8GB. Take note of the End value as you'll need it.

    rm 1 (deletes partition 1, this will erase all data on the SD card)

    mkpartfs primary fat32 0 7425 (creates a new primary partition, the second number should be the value you took note of in the last step minus the size in MB of your desired extended partition).

    mkpartfs primary fat32 7425 7937 (creates the new partition for applications, starting at the end of the last partition and ending on the max size of the card. In this case I used fat32 as I couldn't do it with ext3 nor ext2, link2sd didn't like this format on the flipout for some reason).

    The partitions are created and you should be able to go to the next step.


3. Reboot your flipout with the partitioned SD card, make sure to have link2sd installed.

4. Open link2sd, it will take a while, ask for root permissions (always accept and make sure to have Remember checked).

5. It will ask for the partition type, select fat32. If you are asked to reboot your phone you have everything setup, otherway please post your problem.

6. Once rebooted, open link2sd again and go to settings and configure. I don't like having all applications automatically linked as widgets and this kind of apps can fail if they are on the SD, so I have this setting unchecked. However this is a personal decision.

7. To move an app to the card, hold your finger on it and when the menu appears, press link and confirm.

8. To move an app from the card to the phone, hold on it and press unlink, check everything and wait for the app to be returned.

Further Tips:
  • Avoid moving apps to the SD that are use widgets or that run all the time like: messenger apps, alarm clocks, climate widgets, etc. I tried one or two without any failure but I feel they could be less reliable this way.
  • Don't remove your SD card if the phone is turned on, now it has a partition that is used by the system, if you remove it you could have issues, I would only remove the card with the phone turned off completely and not boot without the card.
  • I made some tests connecting the USB cable to the PC and using the phone in storage mode, the PC could see the primary SD card partition and the phone could still work with apps on the second partition, so it seems to be stable in this sense.
  • If you need to switch to another card, you would have to setup the new card in the same way; I don't know yet if backing up the second partition and restoring it to the new card will work. If your data is critical use some SW like Titanium backup to back up the apps that are linked, remove them completely and restore when you have the new card setup.

So, this has worked for me like a charm, the phone really seems stable and I have so far like 150MB of apps on the SD card. No need to have a newer Android version, it seems very stable.

Disclaimer:
Any process that involves rooting your phone and partitioning can potentially cause data loss and/or bricking your phone. Do this only if you are 100% sure of what you're doing, I will take no responsibility for any data loss / damage caused by this process.

If you have any questions I will be glad to help.

Hi great post above

I rooted my phone and I partitioned my sd card into 2 partitions , both FAT32 primary 3.7GB and when i open link2sd and select either ext 2 or ext 3 I get an error message
"Mount scrip error
Mount scripe cannot be created.
mount: no such device
ext 2 may not be supported on your device. Try FAt32 on the second partition"

Has anyone come accross this problem before ?

Hi,

When you open link2sd,scroll down and select fat32. I tried formatting the second partition with ext2 and ext3 wit no luck. Fat32 is working just fine.

Your guide works great. Finally I can have all apps I like to have installed at once.

I can tell some experiences with backups.

Before I had blur stock rom with link2sd and changed to deblur central europe rom. After reinstalling link2sd all apps where still gone.

And even after restoring all user apps with titanium backup they were restored to phone memory. I had relink them with link2sd manually and to batch restore with titanium backup twice because it broke down in the middle because phone memory was full.

Unfortunately link2sd is no magically way to have them backed up apps and to be independent from the rom. Titanium backup is still needed but that is fine. Nothing seams broken after restore with TI and relink with link2sd.

lovdanie, it's strange, had no issues with the tested phone yet, I partitioned 500mb and it has already like 200-250MB of apps linked and is working great, no issues.

One thing that could have happened is that you removed the SD card. Are you sure the SD card hasn't been touched or formatted?

bagers, it's not really a magical solution, it's just a way to get more space on a phone that lacks internal memory...

miniProBhashi,

That's why I always use CWM to partition the SD card. As I don't have it on the Bllur, I put the card on another phone I have with CWM and it always works... Maybe if you have a linux PC you could do the same thing...

Regards
