Hi I am researching the HTC Aria, and the HTC Eris, and what I am wondering is which of these phones is better? Also is the Eris already discontinued? Has the Aria taken the place of the Eris, even though they are from two different providers? Although the Aria is offered from AT&T, T-mobile, and Verizon, I believe the Eris is only offered from Verizon? Which one is more compact? Thanks in advanced for any help!!
