And a high five to all. I have reached the light at the end of the tunnel. This is a hideous-to-perform upgrade and I don't yet know if it's worth it. I would strongly recommend anyone who has installed additional apps and/or personalised their apps to buy (and use) a backup app first. Why Palmone is releasing an update that wipes the T5 I don't know. Anyway, I did it all as in my previous post and then sat on the train home to get my T5 back to how it was, if not better. Most of the apps came back with the hotsync. I restored my internal drive in its entirety using BackupBuddy VFS Professional (v. 3.1 RC 2) (from www.bluenomad.com with complete ease. I then reckoned I wanted all my preferences back (such as cities in 4cast) and really couldn't be arsed to set everything up again (I ditched my T3 for the T5 because I was so teed off with hard resets) so I bit the bullet and did a full restore from BBVFS. As the Palm reconfigures some things from scratch after the reset (after reading the BBVFS manual) I knew that some files would appear newer on the T5 but that I'd want to overwrite them from my backup to get my prefs. So, using a complicated statistical formula called pot luck, I sat on the train and selectively overwrote anything that didn't look like a system file or a game or font, etc. that I had already got back from the hotsync. I now have an upgraded T5 configured exactly as before (well, slightly better as I changed colours (using Khroma) and fonts (using fonts4os5) again). I also had to pair my BT phone again, but it worked fine on the train, even better now as I can now see its model in the available phones list. I have also set up a GPRS network account in additrion to my dial-up account. I think I have c. 10 Mb more storage now (I didn't write down the original figure), but that might eb just beacuse I've overlooked an app/database or I deleted something to make more space (embarrassingly, my T5 was fine space-wise, but I had to delete stuff off my PC as I had less than the 15Mb required to run the upgrade!). NavMan (my satnav app) isn't happy and I may have to reinstall, but otherwise I think I am a happy camper. More happy, perhaps, that I seem to have successfully navigated my way out of this upgrade rather than because I now have it. So, BACK UP first, read the instructions carefully and check here to see if those who have succeeded reckon it's been worth it.
