For those of you with an HTC Hero on Cellular South, let it be known at Android 2.1 is now ready for you (albeit a little later than we'd expected). It's not an over-the-air update, unfortunately, but we'll take what we can get, won't we?
You'll want to make sure your phone is well-charged before you apply the update (50 percent or higher, please, and Cellular South suggests you install the HTC Sync program beforehand, just in case. CS also is pushing the free trial of My Backup in the Market to back up your contacts, again, just in case. (Can't hurt, but if you're sync'd to Google, you're likely good to go.
You'll also be getting MMS support along with the update, but it's going to cost you $5.99 a month on your bill.
