I've just come across this thread and realised there is an official update from Telecom to Froyo for the i5503T, my issue is even after downloading the latest version of KIES it doesnt tell me there are any updates for my phone. It's running 2.1-update1 build ere27. Any ideas? KIES seems to run and connect fine, I can browse media etc but can't do anything related to firmware.
I'm eager to update to get my calender to sync and sort some wireless issues.
