The process was quite smooth. You hand you phone over and collect it back after an hour.
Some of the changes made
- phone is unlocked by sliding on the screen (no longer by pressing the Menu button)
- slight changes to native Google apps (e.g. browser, Gmail, youtube etc)
- slight changes to layout of settings page
Besides the above, Android 2.1 also opens up the ability to install some apps which were unavailable in version 1.6. Just installed Pocket Informant, and will try it out.
One bad point. The built-in backup programme does not seem comprehensive, as some apps disappeared after restoring the backup, e.g. my paid app, Documents To Go. Will try to figure out how to get that back.
Meanwhile, the HTC Desire Z has landed in Singapore with a retail price of $780...
