In order to pull this off, you’ll need to get a handy little application from the Application Manager. Under the Network section, look for “Bluetooth Dial-Up Networking” in the Extras repository. After you install that, you will want to restart your device. Next, pair your N900 with you laptop (this varies per operating system. I used Windows 7 and these instructions will assume that). After pairing the device, add a new Dial-Up connection on that modem. The phone number will be *99# and you will leave the user name and password blank. Save the connection, but cancel it when it tries to dial (it will fail anyway). Now, launch the device manager, and find the Bluetooth modem that should have been installed when you paired the N900 to your computer. Open its properties, and go to the Advanced tab and set the Extra initialization commands to at+cgdcont=1,"IP","epc.tmobile.com". After this, you should be able to connect to the Internet though your phone.

To prove that it works, I wrote this on the train, and I’m posting while still on the train. :P

I found this particular wiki page to very useful in setting this up, but I found translating the instructions to Windows 7 to be a bit difficult at times.

Done:

• Q1 I/O Reduction goal page up and running (https://wiki.mozilla.org/Firefox/Goals/2010Q1/IO_Reduction) with numbers and bugs
• Review queue neutralized
• Bug 461199 (async visited checks) nearly ready. Working on fixing last remaining failing tests. Two more issues remain to be fixed (other than tests).

• NetUtil.newURI can take a string (plus optional character set and base URI) or an nsIFile.
• A new method for creating channels has been created. NetUtil.newChannel can take an nsIURI, a string (plus optional character set and base URI), or an nsIFile.
• NetUtil.asyncFetch can take an nsIChannel, an nsIURI, a string (plus optional character set and base URI), or an nsIFile.

This means, among other things, that it now requires less code to read a file asynchronously than it does synchronously. The old way to do this asynchronously can be seen here on MDC. This would give the consumer a byte array of the data in the file. Compared to the synchronous case, which can be seen here. Both are pretty verbose and clunky to use. The new way looks like this:

NetUtil.asyncFetch(file, function(aInputStream, aResult) {
  if (!Components.isSuccessCode(aResult)) {
    // Handle Error
    return;
  }
  // Consume input stream
});

One function call, with a callback passed in. There is a slight difference from the old asynchronous method, however. NetUtil.asyncFetch gives the consumer an nsIInputStream instead of a byte array. The input stream is a bit more useful than a raw byte array, although it can be painful to use in JavaScript at times (maybe we need an easy method to convert an input stream to a string?). I look forward to patches using this method to read files instead of doing it synchronously.

Directory structure

In my home directory, I created a new folder called opt.
mkdir opt
You’ll also want to add the following lines to your .bashrc file:
export CFLAGS="-I$HOME/opt/include -L$HOME/opt/lib $CFLAGS"
export CXXFLAGS="-I$HOME/opt/include -L$HOME/opt/lib $CXXFLAGS"
I also created a sources directory, where I’ll be putting all of my source files in.
mkdir sources
We’ll want to be in the sources directory as we install everything.
cd sources

Installation Fun

Install python

wget http://www.python.org/ftp/python/2.6.4/Python-2.6.4.tgz
tar xvfz Python-2.6.4.tgz
cd Python-2.6.4
./configure --prefix=/home/sdwilsh/opt/
make
make install


Install OpenSSL

After you get the source from a mirror and untar it, enter that directory, and run these commands:
./config --prefix=/home/sdwilsh/opt --openssldir=/home/sdwilsh/opt/openssl shared
make
make install

Install Erlang

Note: I had to bump my memory on my PS up to 304 MB (from 150 MB) in order for this to compile. I just doubled it, so you may be able to get by with less. This also takes a while to install.
wget http://erlang.org/download/otp_src_R13B02-1.tar.gz
tar xvfz otp_src_R13B02-1.tar.gz
cd otp_src_R13B02-1
./configure --prefix=/home/sdwilsh/opt/ --with-ssl=/home/sdwilsh/opt/
make
make install

Install ICU

wget http://download.icu-project.org/files/icu4c/4.2.1/icu4c-4_2_1-src.tgz
tar xvfz icu4c-4_2_1-src.tgz
cd icu/
chmod +x runConfigureICU configure install-sh
./runConfigureICU Linux --prefix=/home/sdwilsh/opt
make
make check
make install

Install autoconf-2.13

wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.13.tar.gz
tar xvfz autoconf-2.13.tar.gz
./configure --prefix=/home/sdwilsh/opt/
make
make install

Install Spidermonkey

Note: You many need to install Mercurial. I used easy_install to do.
hg clone http://hg.mozilla.org/releases/mozilla-1.9.2/
cd mozilla-1.9.2/
hg update -r FIREFOX_3_6b3_RELEASE
cd js/src/
autoconf
mkdir build-release
cd build-release
../configure --prefix=/home/sdwilsh/opt/
make
make install

Install libssh2

wget http://www.libssh2.org/download/libssh2-1.2.2.tar.gz
tar xvfz libssh2-1.2.2.tar.gz
cd libssh2-1.2.2
./configure --prefix=/home/sdwilsh/opt/ --with-openssl
make
make install

Install curl

After you get the source from a mirror and untar it, enter that directory, and run these commands:
cd curl-7.19.7
./configure --prefix=/home/sdwilsh/opt/ --with-libssh2=/home/sdwilsh/opt --with-ssl=/home/sdwilsh/opt
make
make install

Install couchdb

After you get the source from a mirror and untar it, enter that directory, and run these commands:
./configure --prefix=/home/sdwilsh/opt/ --with-erlang=/home/sdwilsh/sources/otp_src_R13B02-1/include --with-js-include=/home/sdwilsh/opt/include --with-js-lib=/home/sdwilsh/opt/lib --with-erlang=/home/sdwilsh/opt/lib/erlang/usr/include
make
make install
Note: I feel like I may have messed up how I installed erlang given the strange place it put its header files, but I wasn’t about to recompile it.

Change Permissions & Run

CouchDB suggests you create a new user for to run it is, but this is hard to do it seems, so I skipped it. I did change the permissions, however.
chmod -R 0770 /home/sdwilsh/opt/etc/couchdb
chmod -R 0770 /home/sdwilsh/opt/var/lib/couchdb
chmod -R 0770 /home/sdwilsh/opt/var/log/couchdb
chmod -R 0770 /home/sdwilsh/opt/var/run/couchdb

And now to run CouchDB:
couchdb -b
Sadly, this was taking something close to 500MB of memory. This is far to high for my server to sustain, so I haven’t gotten any further. If anyone has any ideas, I’d be glad to hear them.
