One more time, or the next installment in the Hero upgrade saga

Ok. I’m very nearly at the point where I don’t want to keep posting on this, but I’m eternally optimistic, so here goes:

An internal Best Buy Document has leaked all over Android Central’s best shirt, claiming that the Android 2.1 upgrade date for the eternally neglected Sprint Hero will be the 21st of May.

Now, we all know that getting our hopes up is probably a bad idea, but c’mon, what else but hope can get us through the mid-week blues?

Android and Me have some shed some light on the spout of delays, claiming that they are likely caused by a distribution issue: Sprint wanted to release it as an over-the-air (OTA) upgrade, but the file is too large for their puny servers, and they don’t trust Google’s without running some heavy testing first.

So yes. Let us all set the countdown to disappointment to May 21.
