Review: Motorola RAZR V3xx

Posted on by

V3 Gold The Motorola RAZR V3xx  is one of Cingular's new non-smart 3G phones, and can be purchased relatively inexpensively with a contract. (Amazon sells them for 0.01 with a 2 year contract, cingular charged $79 the last time I checked.) Although it doesn't have a mini-qwerty keyboard and good email support like the Blackjack, 8525, or Treo 750, it also costs $200-400 less. The Motorola RAZR V3xx is in the same class as the Samsung A707 SYNC and the LG CU500 Phone in that it supports 3G, playing music, and Cingular videos, but it's 3G chipset is twice as fast (3.6 vs 1.8).

j2me logoThis is a list of the J2ME applications that I use and like. To make the list they have to be free to use and not have annoying advertising (open source is also a plus).

NOTE:
If I do not list a URL Link, but instead just have a number in parenthesis such as (7223) the number is a "quick download" link at wap.getjar.com.

Enabling the IMAP4/POP3/SSL email client (and other goodies) on a Motorola v3xx phone via SEEM editing

Cell Phone Tower

My new Motorola RAZR V3xx phone is Cingular branded, which means that Cingular has added many money making links to it ("Shop Cingular!") and have hidden some of the nicer features that Motorola originally built into the phone. For example, Cingular has hidden the IMAP4/POP3/SSL email client that is built into the phone. Luckily for me, by changing a few bits in the phone's memory I can re-enable the features I want. I have already fixed Java on my phone so that Google Maps doesn't ask for permission to access the network every time I zoom or scroll, which is another hack I recommend you do to your V3XX phone. Now I will describe the SEEM edit I made.

Creating udev rules to name your devices in Mandriva

I have a Motorola cell phone, and when it is plugged into my linux laptop via a USB cable it appears as a /dev/ttyACM0 device. (Unless I already have an ACM device plugged in, then it appears as /dev/ttyACM1).  BUT, it's much nicer to be able to point my phone programs (such as kmobiletools and moto4lin) at a logical device, such as /dev/mobile where the number won't change than to point it at the kernel device name.

D-Link DWL-G122 works with Mandriva Linux

I purchased a D-Link DWL-G122 802.11g USB Adapter to use with my Mandriva Linux based router and was pleased to find that it worked out of the box. (I was also pleased to find a desk dock for USB sticks included in the box.) Mandriva installed a wireless Ethernet device named "rausb0" which worked just as well as my standard eth2 (built in mini-pci prism card). I verified that the network connection worked with both an access point (managed) network and an ad-hoc network. Continue reading →

Running a physical Windows (XP) partition in VMware from Linux

For the last month I have been able to boot and run my laptop's Windows partition from inside a vmware server that runs under my (dual boot) Mandriva Linux partition. This is very useful when I need to run something in windows but don't want to shut down Linux and reboot.

I found the instructions on Scott Bronson's blog  to be accurate and complete!

Transcoding video to work with Java Media Framework (JMF) on Linux

Posted on by

Using the Java Media Framework is an easy way to build java applications that can record, edit, and play videos, but the number of video codec's that it supports is limited. Unless you want to go with a quicktime format, MPEG1 is a good choice (although the files can be a bit large) for portability. When starting with digital video, you can use ffmpeg to convert and encode the video as follows: Continue reading →
