Upgraded last night, with hardly a hitch. Backing stuff up was the only problem; I *hate* the LG PC Suite, and urge you to stay away from it at all costs. It's slow, bloated, and it screwed up the USB drivers on my PC. Before I installed the suite I was checking daily for updates with the official LG updater,with no problem. After I installed the Suite, it wouldn't recognise the phone. Took a number of USB driver re-installs to get it to recognise it again. And to add insult to injury, the rubbish suite program didn't even work for me. BTW; there's a great free app on the marketplace called SMS Backup & Restore. It'll back up all of your texts (not MMS though) to the SD card, and then restore them after the update. Also be aware that 2.1, as standard, has the option enabled to delete txts over 200 in a thread. I lost a few, and had to re-restore using that app, after disabling the option in settings. Also had some issues backing up my contacts. PC Suite just sat there stupidly, saying there was no connection to the phone. BOUGHT an app (for $1 admittedly) that allegedly backed them up, but then it wasn't available to download in the marketplace. Assume it only works on 1.6. Had to export some partial contacts from another gmail account as vCard data, then import them to the phone from the SD Card. Sadly, all of my Favorites (for some reason) didn't copy over. But, that being said, 2.1 is great, smooth, looks great, runs great, and the update procedure itself only took about 10mins max. Hello Eclair!
