Aanl had a valid concern. Yes, you will loose your apps & settings that was installed ... after a hard reset. All my apps are installed in my SD, so after the upgrade, I only need to create a ".LNK" for each of my apps to the Program group. It's better than re-installing them.
Before you upgrade:
1. Make sure your cradle is power up.
2. Run the Data Backup & MAKE SURE to backup ALL data to SD card.
3. Stop all apps in your pda & desktop.
4. Run the upgrade.
5. After the upgrade, Restore from the SD.
This is mostly Win Mobile 5 (OS) improvement. I 've the A06 upgrade for almost a month. Improvement that I experienced:
1. Registry changes can be implemented instantly; without On/Off or soft reset.
2. No more white screen syndrome: IE displays a Blank Page while it uses an HTTP 1.0 request in a WinInet application.
3. IE & wireless networking/security (SSL, 128-bit encryption): I can do my wireless banking transaction on my X51V now.
4. No need to tweak registry to acescs web sites (bank) that require IE6 or "https". Can visit these sites with original Win CE (IE4) setting:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\Internet Settings\5.0\User Agent:
Subkey "Version=MSIE 4.01"
5. No more On/Off button that require soft reset.
6. Power up sequence faster, i.e. The Start menu comes on almost instantly.
7. Switching between tasks - almost instant.
8. You can Send/Receive (Messaging) all mails (Exchange Server, your ISP, hotmail) thru WiFi internet on your X51V - a real pda.
9. You can configure Pocket IE (thru Registry) to store INDEX.DAT to the SD card instead of having it on ROM. There are 3 Index.dat files that ''grow'' in your ROM as you browse the internet even if you delete the cookies and the temporary internet files. Check Microsoft article KB322916 (they acknowledged the problem but they don't teach you how to fix it).

Over time, your pda will become slow. I will show you how to do it for free without buying 3rd party software in a separate thread.
Check these folders for Index.dat (original 16 KB) in your pda & you'll know what I mean:
• \Windows\Profiles\guest\Temporary Internet Files
• \Windows\Profiles\guest\Cookies
• \Windows\Profiles\guest\History
Note: On desktop, these files reside on the harddrive, it's never an issue.
I certainly recommend it to those who've an X51V. Remember, MS was pushing for the release of Win Mobile 5 last year; this is their OS improvement.
There's no such thing as stupid question; just ask.
