The fastest that I've found were,

prl 45713, and prl 42900/60683 both getting about 500-660 kbs on the app 'speed test.'

I've also tried doing the *228 programing and it loaded my phone up with prl 45565 which gave me horrible internet speeds something like 10kbs on speed test.

The two prl's that I mentioned can be found on the Prl Sticky, here is the link.

If anyone can share some prl's that they've found for their 'evo 3d' it would be appreciated.
