Dell Streak Andriod Update

This weekend just gone I finally had enough of the bloated, slow, unreliable Dell/o2 ROM that had been installed on my Dell Streak.  So as the phone had already been rooted, (rooting is the act of getting full control of the super user or 'root' user to give you access everything) I decide to give a new ROM a try.  Being that I have a almost dead bit of hardware, that didn't sell well, mainly due to the issues I mentioned above, along with the bad delivery times when they did update it was going to be trouble.  While their are a number of people out there developing ROMs for this device its much smaller community then say those for the Samsung Galaxy S.
The main trick seems to be getting the ROM on, which was helped with a tool called 'Streak Mod recovery' as the other ROM managers don't work with the Dell Streak.  Once this is on you can get the ROM on and get the device updated, so lets got though what I did and can remember.
First I would say you need to get a backup of the system, in my case I use Titanium backup, its a pay for app but well worth it.  Something you need to remember is that if you move from one version of Android to another then you might find it does not recover correctly, for example my default ROM is 2.2 and not all install correctly on 2.3.  Some do work, like Angry Birds Rio is fine, but original Angry Birds just crashes and has to be removed and fresh installed from the market loosing any data.
Once you have the backup I recommend looking at this guide to install 'adb' and 'fastboot' which are utilities you enable you to access parts of the device to update the files to do the install - ADB/FASTBOOT
Once this is done you need to look at installing the 'StreakMod' to force the recovery of the ROM in place of the default system recovery, which this link covers - StreakMod
Once that is done you can simply download a ROM zip file and store it on you SD card, and use the StreakMod to recover it.  Now their are a few ROMs out and about and I have tired a few, CyanogenMod is still in development and not ready to be used, StreakDroid works but I have found stabilization issues.  StreadDroid is 2.3 so lots of old app backups will not recover correctly, but the one I have install Simple Streak 1.2 is Android 2.2, so works well.  The guide for this too can be found here - Simple Streak 1.2, its nice and light almost all the unimportant apps removed for a nice speedy ROM.
I did find one issue, as this has been developed out side the UK the default gps doesn't fix correctly.  But after some hunting about I found a fix, so here it is -

adb shell
su
mount
mount -o remount,rw /dev/block/ /system
vi /system/etc/gps.conf
mount -o remount,ro /dev/block/ /system
