The last time we caught wind of an the possible update to Android 2.1 for the HTC Hero (on Sprint), the carrier stated
this would be happening at the beginning of Q2, 2010, but didn´t mentioned an exact date. Now a leaked document has surfaced on the Internet and it reveals the smartphone will get its software update on April 9. Hold your horses, however, because no one has ever stated the update would update the OS version of the HTC Hero to edition 2.1. Rather, the paper clarifies this would be a patch to fix the issue with the images in Sprint Picture Mail. Despite that, the source assumes owners of the HTC Hero will not be disappointed and will be able to finally see Android 2.1 on their devices.
We know this does not sound very reassuring, but fingers crossed the April update will finally bring all the extra features that Android 2.1 offers. If you have more information on the matter, please share it with us via this link
