Hmm, that's weird Kreeeeeeeeeeeeeeeeeeeeee.
You can update a number of ways, I use Android Flasher, you can also use Recovery if you're not on a custom HBOOT yet (stock) or ADB as well. I think there's an app to do it as well similar to ROM Manager.
I seem to have an issue with my Desire on LeeDroid 2.3d
Over time, Launcherpro just seems to get slower and slower and sometimes hangs just waiting for itself to refresh
Is it normal for the Desire to slow down over time??? Not got a massive amount of apps on there and using the EXT partition on a 16GB card.
Odd, mine has been doing this over the past few days, and I have to force close it.
Running CM7 on mine though.
I've wiped Dalv cache this morning and things seem to be OK at the minute.
