depends on ur need, bro. what do u prefer actually? do u really require that 8.1 or what..always ask back urself.

ini macam ar... have to ask Neo users as im a Pro user. nowadays printers are just 3in1 with scanners along, rm3xx only mar..

the different between Neo-V and Neo is the camera. Go for Neo for the better 8.1MP camera.

Neo-V downgraded to 5MP because of the deadly Japan earthquake took lives and brought the local electronics industry to a halt. Sony was affected too and, with a shortage of 8 megapixel camera sensors looming, someone had to take the hit. That someone was the Xperia neo. This is the story told by a company insider, who we have no reason to doubt.

V means 5, or value?

Trust me, you don't really need a faster phone that drain your battery faster, because you won't be utilize the extra mhz. Besides, Neo and Neo V had the same 1ghz Snapdragon processor so they should be the same. SE is somewhat optimize their firmware that it run things smooth even with single core.

As for the ICS issue, don't worry as sooner or later you'll get them, as SE promised. Not like without that your phone cannot run.
