We previously reported that the European HTC Hero could see an update from Android 1.5 to Android 2.1 at some point in February.  At the time, we were told secondhand that HTC Poland was pushing out the update.  We've learned today that Irish wireless provider, Meteor, has been in contact with HTC and is advising a March rollout.

Just got another update on this and HTC have said they are releasing 2.1 on the Hero and we are hoping to have this availible (sic) by the end of March...This will be available via the HTC website and we are also looking at other ways to make this update easier to access for our customers. - Meteor Forum

We're still waiting to hear when Sprint plans to update their Hero or what Verizon is doing with the Droid Eris.  Last we heard, an update to 2.0 was slated for this quarter.
