I'm currently using the Aurora Rom and it's working excellent with the exception of two things:
I'm using a domestic roaming SIM (I think that's what it's called, my provider borrows network capacity from another provider) and the phone is acting a bit odd.
1. There's no icon to indicate what sort of data connection is currently active (edge, 3g, hspda etc.),
2. The phone randomly either A: Says I can only use emergency call and it indicates there's no signal, or B: Says there's no SIM-card present. Both of these can be resolved with rebooting the phone. They seem to appear at completely random intervals, but at least several times a day.
Neither of these issues are present if I use my work SIM which is the same provider as the network, I have a data connectivity icon and there's no fuzz with the SIM-card.
Both of these issues has been present at all versions of Aurora that I have tested.
If it is to any help I'm using a provider called OneCall in Norway.
