Thread: Hero os on a G1??

Ok my 1st taste of android was in the form of a HTC HERO and i gotta say, I loved it! well not so much it's looks but it's abilities and os, sadly it was a carrot dangled in front of my face by t-mobile to encourage me to stay and have a new 2 year contract, I almost did bite but reluctantly returned it within 14 days and said no! Since then I bought a g1 on ebay and I am quite happy with the slide up screen with the keyboard however the os is different and I fell in love with the 1 on the hero. so my question is.... is it possible to put the hero os onto the g1? As far as i know the hero had 1.5 cupcake but I had that on my g1 and it was totally different! any help on this???
