hey guys,
I've always looked for application on my itouch that'll help me to make chemical formulas, quick database sheets, and basically anything chemistry related.
Just recently I got something off the applications called 'iMolebuilder' it SEEMS pretty good (kinda tricky to use and I've only had it for an hour or so, so I can't say whether or not anyone else should buy it.) but one of it's functions is that it can download specific molecules off of specific sites (at least I think so)  So I basically have two questions for anyone:
1.  Does anyone have some good sites where molecules can be downloaded?  Doesn't matter which ones, I'd just like to get as many in my database as I can
2.  Has anyone else gotten the Imolebuilder?  If so, could you maybe link me up/post up a guide for how to use it?  I'm managing to navigate around decently for now, but it'd help if someone who knew better could give some advice.
If no else does I'll try and post a review/online guide to using this application once I figure out how to use it better.

Hi There
I've got the iMolebuilder and have found the following sites to download from:
www.molecularmodels.ca
(e.g. www.molecularmodels.ca/molecule/pdb/bh3.pdb)
www.chem.arizona.edu
(e.g. www.chem.arizona.edu/~salzmanr/molecules/n2.pdb)
www.chem.lsu.edu
(e.g. www.chem.lsu.edu/lucid/maverick/Al2O3.pdb)

I haven't got any instructions, and haven't got the hang of crystals yet, but I've managed to build relatively simple molecules like sucrose from scratch, albeit in a rather qualitative way, i.e. not going for precise bond lengths and angles.
If you've got any specific questions then try me, I might just have hit on it!
Cheers
