Question 1

How big is it, in length?

Accepted Answer

Almost same with iPhone , price not good, buy LG

Question 2

can this phone work on AT&T network?

Accepted Answer

I do not know myself.  I ordered the phone, but returned it before opening it.  I re-read the description for the version of Xperia M I ordered and it said it was compatible with AT&T's 2G.  It did not mention 3G.  So my assumption is that it will work on AT&T, but it may not work with their 3G network.  I know this does not answer your question, but maybe someone can answer if the phone is compatible with AT&T's 3G network.

Question 4
