[WTB] Cheapest Xperia mobile supporting LTE in US

[ppgsk17]

I recently moved from India to US(Bellevue,WA). I am having ZR(C5502) but facing network related issues as it doesn't support LTE.

I am using T mobile connection and I want to buy cheap Xperia phone supporting LTE.

What are the options available here?

Also is there anything I can do with my ZR before purchasing a new phone?

Thanks in advance!

There's nothing you can do with the ZR to make it compatible with T-mobile USA 4G frequencies, you could check bestbuy and look for the T2 Ultra for $299. 

or check SonyStyle

After some research I found out that M2 (D2303) is the cheapest handset I can get here.

How are the reviews of M2? Any cons for M2?

And which is the better one M2 or M2 dual?

BTW M2 available at around $215.
