Viewsonic V37

I bought a Viewsonic PocketPC mid to late last year and forgot to post anything about it.

I bought a Viewsonic V37 for $100 used on ars technica classifieds. It has the following for specifications:

  • Intel XScale™ 400MHz processor
  • Microsoft® Pocket PC 2003 Premium Edition*
  • Includes 64MB ROM and 64MB SDRAM (36.45MB user accessible)
  • Light: 4 ounces
  • Long life lithium battery lasts up to 8 hours**
  • SD/MMC Expansion slot

* It came with PocketPC 2002. Apparently Viewsonic had the update but was neither giving it out nor selling it anymore. I was able to locate it and have it archived. If anyone also needs it, comment on this post and leave your e-mail and I can get it to you.

** This has not been what I have experienced.

The pocketpc has been nearly flawless for me. It is the same speed and about half the weight and size of my previous PocketPC: Dell Axim X5. There are a couple of pros and cons of this PocketPC compared to some others I’ve had:

+ Small, light, sleek design.
+ Bright, crisp screen.
+ Fast, still one of the fastest on the market.
+ SD expansion slot is great for storage.
– Short battery life, especially for games.
– Very poor dial. Sticks, and plain doesn’t work sometimes.
– Some game incompatibility*.
– Synching issues**.
– Lack of general support***.

* I have tested MANY games on this PocketPC. Of all that I have tested, only about 3 have not worked. The main game that I am upset about is Worms World Party by JAMDAT. It simply does not open.

** Every once in awhile, the only computer I have my V37 linked up to will report the device as an unknown device. To fix, any of the following have worked for me in the past:

  • Unplugging/Replugging
  • Plugging into a different USB port
  • Reseating the V37 in the synch cradle

*** This PocketPC is nowhere near as popular as Dell or HP PocketPCs, and I have found very little support overall for this brand. Viewsonic only made 2-3 PocketPC models; the V35-V37, all of which are out of production. Don’t even think about contacting Viewsonic for support, these are all out of warranty.

Overall, I would rate this PocketPC an 9/10. It is my 5th PocketPC, and it is by far the best.

Edit 6/21:
Someone’s been looking for the v35 and v37 ROM upgrades, so I posted it for download with tracking:

Edit 2008-12-12:
Wordpress 2.7 broke my download script, so here’s the direct link.

    Thanks a lot for hosting the ROM here – I know this is a really old piece of kit, but no sense sending it to landfill just yet!

    I’ve just replaced the battery in mine (There’s a great seller on e-bay for batteries for these if anyone’s interested by the way)… I replaced the battery as the original one had finally given up the ghost.

    However – I now have a problem – I can’t get windows to see the device (it wouldn’t before I changed the battery either – I had hoped the new battery would solve this problem!)… This means, not only will it not sync (not really bothered about that!) but also I can’t flash the ROM!

    I’ve tried copying the files to the SD card and using the flash from SD option in the update util on the device but it doesn’t seem to do anything – comes up with a few messages acknowldging the card but that’s it)

    so – please, does anyone know how to flash this using the flash from SD card option? I’m stuck and out of ideas!

    Thanks in advance,

    can someone please post a link to the downgrade WM 2002 installer? I have called and emailed viewsonic, but they won’t budge with a ftp link.

    I found a download link to get the zip but using windows 7 i cannot get the usb upgrade to work. if i copy the .bin file to the sd card and try the upgrade using sd card it gives a ‘open ce image error’ message.

    i am assuming that the .bin file needs to be a specific name or in a specific folder but i cannot find any instructions on that. i’ve read all the comments but there are no specifics, just talk about downgrading to 2002.

    i imagine the process is the same either way, so can you help me out with those directions?

    thanks! and thanks for keeping this thread alive!

    – mike

    I am so desperate for this file, but alas the link is broken. I know you posted this AGES ago, but is there any way you might be able to send it to me?

    I found the file but I can’t get mine to go into upgrade modem no matter how many times I repeat the process.
