June 2011--best way to root an HTC Sprint Hero?

[mikeinstlouis]

First of all, I am SORRY if these questions have been asked before, but I can't find them.

Also, if this is the wrong spot, please let me know where it should be rather than making snide comments like on another site.

I have successfully rooted my EVO with unrevoked. Now my brother wants me to do root his Sprint HTC Hero

Here are my questions.

I see that there is an download on unrevoked, but his radio is 2.42.02.10.29 and this is not listed. Is this an issue?

Is there a downside to having to use this unrevoked forever?

All that he wants is to do is get a bigger SD card so that he can move his apps off his phone and put more on his SD card. Is this possible? Even without rooting?

I don't think he cares about ROMs or tethering. He just wants to move some of his apps to an SD card and I don't think it is possible without rooting.

Thanks, any help would be appreciated.
