Two really interesting new phones are soon to be released on T-Mobile, the Samsung Hercules and the HTC Ruby. We now know at least a tentative date for their arrival, October 26. Both of which are "4G capable and share many similar top of the line features and also [are] the fastest smartphones in the market" according to T-mobile. I'm not sure we can argue too much when we have a look at the rumored specs of them: a 4.3 inch qHD display, 1GB RAM and a 1.5GHz dual-core CPU for the Ruby, and 4.5 inch Super AMOLED Plus, 1.2GHz dual-core CPU, and 16GB of internal memory for the Hercules. Either looks like a real winner, and should make any Android fan pretty happy.
Of course, these dates are likely as not to change, but at least we know the ballpark.
