The Edge guitar and Amps Software

[katambe]

Hello there
I recently bought the IK multimedia's stealthplug, to connect my guitar on the pc, and i tried the Amplitube live as well (included in the S.plug box).
Its fantastic how this software+hardware works! Another one i've tried is Guitar Rig 2. Its almost the same, but it has diferent graphic aspect.
My questions are:
1-Does this softwares can make configurations possibles to play some the edge riffs/tunes???
2- Can someone place or share some presets over the internet?
3 -Any one knows places in the internet where i can find some u2 presets for these 2 softwares??

Thanks to all!!!
