I bought HTC hero today. So far it has impressed me with its Android operating system and the HTC hardware itself.I used iPhone for the last two years, so I know what a good phone and os can do. It takes a special phone to impress after that kind of experience, so far HTC hero is doing that.More detailed review at a later date.The phone I bought was locked, or at least that's what the person at the store said. It even shows Airtel logo when it boots up, but once I put my aircel sim it started working right away. No unlocking necessary.
