Correct, I'm actually in a similar situation. I bought the Galaxy SII on Friday but haven't opened it up yet. Now I see the One V for $50 and I'm second guessing my S2 purchase if only for the price. I don't want to give up my $25 a month plan either, but my Triumph has the widely talked about me memory issue.
Yup I'm in the same boat. I want to upgrade my Triumph but $25 a month is so good. I'm considering going to T Mobile for the $30 and then picking up a Nexus.
