Definitely android. Trust me ive had my andriod phone for over a year now n i couldnt be more satisfied. Once you have an andriod youll never want to switch. My brother traded his mytouch for the hd2 n in less than a month he got rid of it cuz nothing compares to the awesomeness of an andriod. I suggest u get the new galaxy s phone. Samsung has slighty different versions of it on tmobile atnt n i think sprint is getting theirs soon, if they dont have it already (n sprint's has a keyboard added on). Anyway no matter what network u have the galaxy s is an awesome phone.
