The pr1.2 system update downloads but fails to install. I've clicked re-try and it downloads another 1mb and then fails to install. I've tried this several times - always with the same results. The wlan connect keeps dropping (even though it was fine and I was able to download the 283mb update). There are 14 other application updates available. I've been able to instal several ofl them. Maps update won't install - says it needs system update. Does anyone know what is going on or how to fix it?
