The Sony Xperia ZL has been available from the Sony website since March, but if you have been waiting for their Xperia Z, then your day has come. The handset is now available through the US Sony Store.
The device is available unlocked, in black, white, and purple colors, with a price tag of $630. But, it will only work on AT&T’s HSPA+ network, there is no LTE.
Fortunately, Sony has decided to ask the same price for its Xperia ZL. So for $630 (down from $760), you can choose the ZL with LTE and the same hardware as the Xperia Z, though no water-resistivity. Or you can simply wait for an official LTE version to launch on AT&T, although there is no certainty about that happening. There have also been rumors and leaks about the Z heading to T-Mobile.Source]
