I'm still running 10.3.9 on a Powerbook G4 (ancient by now, I know). Me.com requires me to update Safari/Firefox, but updates to those are only available for 10.4/10.5. Is there a solution for this? Or should I just forget about push, etc. until I'm ready to get a new mac? Will this essentially just reduce the iPhone to a sync device rather than a push device? Thanks.
