Besides plugins for the W810i, the guys at Mobile.Feisar.com have also developed a plethora of plugins for other Sony Ericsson models as well. Worth a look, if your Sony Ericsson cell phone currently, doesn’t work with iSync.
There are also themes, ring tones, screensavers, HID remotes, Java applications/games and a host of other software aimed at enhancing your Mac + Sony Ericsson experience. One app to look at is Sync Now which provides a workaround the missing one-click syncing (albeit that it doesn’t actually sit in your menu bar), that used to function in Mac OS X 10.3 Panther but has since been displaced in iSync 2.2 in Mac OS X 10.4 Tiger.
In a nutshell – there’s heaps of information at Mobile.Feisar.com that you’d want to check out if you’re a Mac + Sony Ericsson user.
“Great work guys!”
