tar zxvf the file, copy the contents over to you clean 2G SD card (formatted to FAT32), place the SD card in your powered down warp, power up, make and drink a coffee.
Now you have a nice new clean warp with the latest and greatest.
Pop in you GSM SIM (no need to power cycle). On the Asterisk command line type gsm show status and you should see your mobile operator connection listed.
Good to Go!
