    You have to make the make the filesystem read/write:

    mount -o remount rw, /

    And when you are done, make it read only again:

    mount -o remount ro, /

    And I am not seeing any difference speed-wise. It was worth a try though. Trying the TV hack next...

    champiful - you need to remount the file system. run:

    sudo -i
    mount -o remount,rw /

    Then make the changes to the files via the method described. Once you are done, just to be safe, remount the filesystem back in read only mode by running.

    mount -o remount,ro /

    Or, you can install nano via the following command(assuming you have optware installed)

    ipkg-opt install nano

    Then use nano instead of vi. Its much easier, even a caveman could do it.

    Some of you noobs are really going to F your phone up one of these days. Just blindly typing things that people say on a message board into a rooted Pre's terminal without fully understanding every command will eventually get you a bricked phone.

    I haven't done any speed tweaks (yet) and I just got 1.22 Mbps on mobilespeedtest.com.
    Palm Pilot -> Treo 650 -> Treo 755p -> Pre -> iPhone 4s (Sprint)

    You guys are the bomb! I know that the possibility to F my phone up is high especially for a noob like me, but the temptation is just too great. At least I got insurance right? Aint nothing like learning from your mistakes.

    I know I posted in here before that I thought this wouldn't work.. Well I tried this today and WOW the internet got faster... Its nuts now.

    Between this and the other tweak my internet seems to be twice as fast as before. Websites i've never been to before on my phone are loading as if they were already cached!!

    I've only bricked my phone once, and all it took to get it back was the webOS doctor. I'd say the real noob here is the one who doesn't understand that rooting your phone won't allow you to permanently brick your phone.

    I didn't expect it to work either, but I'm glad it does. Its a very nice upgrade.

    You can also mess with these if you know what you're doing. This script is called when starting your EVDO in /etc/pmnetconfig. /proc/sys/net is where linux network tuning parameters are kept, although a lot of this is based upon the type of network you are on. There are a lot of linux tcp tweaking guides but they are assuming 100Mbit or GigE lan for the values. CDMA is a whole new ballgame. Not only that but the 2.6 kernel is supposed to be adaptive in these values per your environment. I wonder why they hard coded them. The Pre is running a newer kernel than the latest RHEL!

    #!/bin/sh

    source /etc/pmnetconfig/funcs

    ${ECHO} '262144' > /proc/sys/net/core/rmem_default
    ${ECHO} '262144' > /proc/sys/net/core/rmem_max
    ${ECHO} '262144' > /proc/sys/net/core/wmem_default
    ${ECHO} '262144' > /proc/sys/net/core/wmem_max
    ${ECHO} '1' > /proc/sys/net/ipv4/tcp_rfc1337 (hehehehehehe)
    ${ECHO} '180' > /proc/sys/net/ipv4/tcp_fin_timeout
    ${ECHO} '60' > /proc/sys/net/ipv4/netfilter/ip_conntrack_udp_timeout

    ${ECHO} '6' > /proc/sys/net/ipv4/tcp_retries2
    ${ECHO} '4' > /proc/sys/net/ipv4/tcp_syn_retries


    NetCfgCalcPrio ${CMUSBINTERFACENAME}
    ${LOG} "${IPROUTE2} route del default via ${CMUSBDEFAULTGW} dev ${CMUSBINTERFACENAME}"
    ${IPROUTE2} route del default via ${CMUSBDEFAULTGW} dev ${CMUSBINTERFACENAME}
    ${LOG} "${IPROUTE2} route add default via ${CMUSBDEFAULTGW} dev ${CMUSBINTERFACENAME} metric ${CMIFPRIO}"
    ${IPROUTE2} route add default via ${CMUSBDEFAULTGW} dev ${CMUSBINTERFACENAME} metric ${CMIFPRIO}

    if [ -e ${NETCFGTMPDIR} ]; then
    ${RM} -rf ${NETCFGTMPDIR}
    fi

    ${MKDIR} ${NETCFGTMPDIR}
    ${TOUCH} ${DNSMASQSERVERCONF}
    ${START} -n dnsmasq

    NetCfgClearDns



    I also noticed in a config file somewhere that the luna interface is limited to 10MB(or 12, I was looking at a lot of stuff yesterday) of ram. Lots of pre-hacking possibilities!

    Doesnt really matter, all # does is comment out a line. This is what the first few lines of mine looks like:

    root@castle:/etc/ppp# cat options-cdma
    # /etc/ppp/options-cdma
    #
    921600
    crtscts
    local
    # Run the executable or shell command specified after pppd has
    # terminated the link. This script could, for example, issue commands
    # to the modem to cause it to hang up if hardware modem control signals
    # were not available.
    connect /etc/chatscripts/connect.chat

    precentral and webos-internals are great sites. I'll be up to speed eventually.

    Ok, for anyone wondering: The PRL list is located in a tarball in /usr/lib/modem/cdmaCust.tar, untarring this gives me Sprint_<zip code here>.prl, however the file is in binary. Are there any programs to edit .prl files? I know some prl hacking is going on out there. Ever since US Cellular installed service in the subway here, I cant get service. Use to default to Verizon and work fine, but now it doesnt. So I'd like to edit Verizon to take priority. Ideas?
