We have an i9000t here that we use with active sync/exchange 2003. I am having a few issues with this.
When we get an email forwarded from an HTC Snap (possibly any WinMo6.5 phone) it forwards it as an .eml extension..android 2.1 update 1 (the latest avaliable telecom rom) seems to have issues with this, as in it can not open it.
Other problem I have is the phone always seems to default to the internal my calander rather than the active sync calendar, I don't want it to do this. In fact I want to remove the my calendar all together, I want it all to sync with my exchange calendar.....
Due to this being used in a business I'd really rather not play with rooting the phone using non telecom offered roms.
